Never Back Down – Tidal Mermails

jeff jonesWith so much hype going into Dragon Rulers and Prophecy, the previous best deck has dropped a lot in popularity. A couple months ago, Abyssmegalo was a $100 dollar card, and now is hoovering around $60.

Now then, many of you probably still have your Mermail cards, and right now, Elemental Dragons and Prophecy are EXPENSIVE. I doubt many of you readers today have been able to obtain the entire Dragon deck (but if you have, kudos) and if you have Prophecy, well, I'd be willing to bet you never were a fan of Mermails to begin with. Question of the day, just for my own curiosity; If you played Mermails as your main deck prior to LGTY, are you/have you given any thought to running Prophecy now? Leave your answers in the comment section.

Anyhow, Tidal, a Dragon Ruler as well, goes hand in hand with the Mermail deck, making it even stronger then it was before. Mermails can go toe to toe with Elemental Dragons, as they still have 2 card OTK's and can still make Abyssgaios to help control the opponents rush of Big Eyes and Dracosacks. However, so far Prophecy is a bit more of a struggle to fight against. Spellbook of Fate is the answer to just about every card in the game, and it's just really hard to come back from the turn 1 Judgment + 3 Spells.

Anyway, at my locals currently my deck of choice is Tidal Mermails, so here's what I'm rolling with currently

deep sea divaSo for the Tidal lineup, I'm using 2 baby dragons and 3 Tidal. I really like the baby dragon as being able to put more level 7's on the field, allows me to make Big Eye against Prophecy, which hopefully game 2 will allow me to Eradicator them for all of their Spell cards. Also, it allows you to Xyz for a Rank 7, remove the Tidal as a material, then summon it back to the field again.

I cut 1 [ccProd]Deep Sea Diva[/ccProd] for room for other cards which I felt were important, one being a third Abyssgunde. I kept needing another to search off of Spikes and Abyssteus as I didn't want to search for Linde/Marksman, and in combination with Tidal, is very good as you can discard it with Tidal, and send any Mermail to grave which Gunde will bring back.

3 [ccProd]Effect Veiler[/ccProd] help in almost every matchup. And when you can, I use it to make [ccProd]Crimson Blader[/ccProd] with one of my Level 7 Monsters in order to shut down Dragon Rulers, and hopefully OTK them next turn.

Moulinglacia was added because the graveyard is so ridiculously easy to manipulate now with Tidals existence.

Currently, Typhoon is not that great of a card, so I moved it to the side deck. I rely mainly on Marksman to deal with backrows if need be. Right now, this deck's biggest weakness would be Evilswarm, so again, I make sure to have a good side deck for that as well.

With Tidal out, I've cut [ccProd]Pot of Avarice[/ccProd] and Abyss-Squall just leaving the deck with 3 Abyss-Sphere for Trap cards..

The extra deck is more tight then ever. I cut all level 7 Synchro monters for things which help win games, like [ccProd]Crimson Blader[/ccProd] and of course the new Dracosack (if you dont own one yet, dont worry, neither do I.)

The deck still plays almost the same as before, just has more options, and of course more options, the better. Tidal is just such a good card it just pushes Mermails further then before.

I judged the ARG Regional in Ohio, and witnessed many more Mermail decks then I thought there would be,  try to take on Prophecy and Dragons. There was one player who I kept an eye on who was doing very well, but unfortunately do to some mistakes he lost some games against Dragons (ones he should have won) which knocked him out of the tournament. Most of the Mermail decks ended up 7-2 or 6-3. So Mermails aren't totally down for the count, we just have to find a way to better adapt to the meta.

Focusing again on the Prophecy matchup, Eradicator Virus is probably the best way to deal with them, but it's still not enough. Something some OCG decks have been trying is Anti-Spell Fragrance. The card if drawn early can shut Prophecy down for a turn, allowing you to hopefully OTK them, or use Marksman to pick off their important Spell cards. I myself haven't had a chance to try it yet but it's certainly something to keep in mind.

Evilswarm OphionFinally, the Evilswarm matchup which is probably the most annoying, is the deck where you have to sacrifice your game 1 probably in order beat your other matchups more easily, since Evilswarm is the lesser played of the popular decks. With lack of MST and focusing more on Monsters, the deck is more vulnerable to Ophion then ever. The match-up isnt unwinable, its just very unfavorable, so again it's important to make sure you're siding things like a third Infantry and such to deal with it.

So concluding all of this, until/unless I find something nifty to run, I will probably be using some sort of varient of Mermail. Good players can still make the best out of the deck to set up great fields against Dragons, and Mermails basically destroys most rogue like decks, so with the exception of the uphill battles of Prophecy and Evilswarm, you should easily be able to win. Mermails is a very unforgiving deck in the sense that if your opponent screws up, they are very likely to just get OTK'ed in the following turns.

So duelist, until next time, good luck to everyone for their Nationals testing. Play hard, or go home.

    I wonder if you will adapt changes for No. 74 Master of Blades. im testing the deck with one Forbidden Chalice, double breakthrough skill

  • Prince

    I’ve been playing a similar version on DN lately. I’ve had no problems with Verz, Dragons or Spellbooks but to be fair it is DN and they’re not know for having the best of players. Sadly I don’t have the money for Megalo else I’d try it at my locals/regionals. Anywho, this is what I’ve been running:

  • RaiXUchiha33

    Surprise no breakthrough skill Jeffy

  • Jason Acosta

    Ive been testing 1x Dragon ice, though it seems strange i think the card is powerful. its searchable through tidal, its a level 5 making it easier to go into gungnir along with keeping diva’s free monster. but the most amazing part is its effect in grave. you can still activate dragon ice in the grave pitch a gunde or blah blah get him back and either stall with a lvl 5 2200 def or pitch the gunde get things back and own. Dragon ice can pitch himself in the hand to special which i think is amazing too, idk im still testing it but im liking it.

  • Jarret Zimmerman

    No Max ‘c’? I would have liked to see breakthrough skill in here as well. It helps the spellbook, dragon, and evilswarm match up just too much. Also amazing against water.

  • anonymous

    Jeff what do you think about Maxx C?

  • Steve Weigner

    Have you ever tried teching in 1 Tridon and 1 Poseidra for more easy level 7 access?

  • Josh McPeake

    Yeah, I just started using mermails and I am trying to get a build that will still win this format, I have been testing seven star sword to get rid of those annoying leed hands and also you can use it on tidal ovviously, but the beat play is stealing level 7s and using it on them. also I am using 3 infantry and 2 marksman because if you are playing a lot of Teir decks then all backrow essentially is chainable and marksman is pointless on them where as infantry gets rid of every annoying card. veiler is boss this format, I win lost of games from prophecy relying on magician effect and veiler stops their whole play and as Jeff said crimson bladder is a card. mermails still have the potential to win.
    and as the other guys said dine is shit because you can’t use it that way.

  • spencer johnston

    question of the day: i’ve played mermail a while and no i would not go to prophecy. doesn’t fit my play style, i’d go to dragons if i switched, which i very well may.

    question for jeff is, when are you or billy going to go to a regional and prove to us you can still win it all with mermail?

    • Dustin Adams

      Billy’s playing Dragons now.

  • Thomas Chacko

    you used then a lot instead of than

  • Aaron Doucette

    I think you also forget the other annoying matchup that happens when a certain other variant called Constellars face Mermails happens Jeff. Great article however I played Constellars yesterday and saw more wins against Lswarm then against Constellars due to the versatility they bring to the table with the support of Fire Fist Bear, Maxx “C”, Veiler, and T-Kings Main Decked. Not to mention their Extra Deck pretty much makes a good and easy way to deal with the exact same decks that Lswarm can beat if not more. Not to mention a side deck consisting on 3 of each of the following cards pretty much sets up for an easy defense against both this deck and the other two meta decks of the format: Deck Lockdown, Dimensional Fissure, Gozen Match, Imperial Iron Wall, and lastly Macro Cosmos.

    Again Great article but never forget other decks that have the potential to give something like these a difficult matchup especially game two and three.

  • Carlos Martell

    Jeff, to begin with , awesome article.

    Now as a tidal mermail player, i must said that i loved your build to first sght, thus is very similar to mine. The main strong diference is that im playing abyssdine, that little mermaid is just awsome, just go first turn sphere / linde then pike, pike for dyne, dyne ss… ss linde, so in your turn you get some out to the ophion pest, like zenmaines or temtempo.

    Just saying because i got awesome results at my locals going into that first turn play in mostly all of my games, 2nd place in a 80 person tourney, so i asume that is ok.

    Also with the higher monster line up, salvage its just more valuable.

    • Aaron

      You can only use one effect of Abyssdine per turn. In your example, you used two effects of Abyssdine.

    • Billy Belmont Valo

      If that was a legal play, i think more people would be playing dine, too bad you can only activate 1 of dines effects per turn, nonetheless, its still an ok card for a temtempo play.

    • Alex Little

      you can’t legally make this play…

  • yolo420cashmoney

    Great Article, but why do you not play Maxx “C” in the main?

  • djdon

    What is your side deck?
