Elemental Dragon in everything

Quick post, as I'm still waiting for LTGY

• Tempest: It needs the deck to have WIND monsters and Dragon monsters, so it's not too hot (discard Red-Eyes Wyvern for Red-Eyes Darkness Metal Dragon anyone? Or discard Luster Dragon #2 for a random Hieratic) Dragunity is an obvious choice if you like Tempest (Gold Sarcophagus for a free Phalanx/Mystletainn), Harpie is decent too. However, I rate this card as "average" overall (2400 ATK). Aside from the Elemental Dragon deck, you'll rarely see this card in play except in Dragunities.
• Blaster: Laval, Fire Fist. The destruction effect of Blaster is much more useful than Tempest's restricted search. He can also feed the graveyard for Rekindling/Brotherhood of the Fire Fist Spirit. I suppose this card will make Laval much better than the old version, considering a single Rekindling + Blaster in graveyard = madness (Librarian + 1 level 5 synchro + 1 level 8 synchro and you haven't normal summoned), AND the destruction effect may work as a pseudo-MST, which is really needed for the deck. Other than that, Blaster is not too useful either, since there're not many good FIRE-based decks out there
• Tidal: It's for the WATER deck (and recently people usually call Mermail WATER deck). It's pretty much design for the WATER-based deck. Even though Tidal's effect is the only -2 effect of the 4 dragons, it's very useful in WATER decks as most of them rely much on the graveyard. Tidal + Abyssgunde = any Mermail from your deck, and Megalo discarding Tidal will immediately put 2 level 7 WATER monsters on the field for Big Eye or Abyssgaios. Speaking of Abyssgaios, it's one of those reasons why Tidal is so good. Abyssgaios is too good (until people switch back to Undine build, like I have). Frog-based deck also gets some boost because you can kick Swap Frog and Salvage it back, or kick Nimble Angler for mad summoning
• Redox: the best of all IMO. It turns every explosive EARTH decks out there (Karakuri, Geargia, Gadget) into really really fast-paced deck. In Karakuri, you have Iron Call for the same purpose, but Redox can summon the discarded monster which is great in many situations. In Gadget, Shock Master is now easy to make, and Big Eye + Dragosack will be 2 continuous threats as the deck can literally summon 2 level 7 monster (the other being Machina Fortress) for free. In Geargia, if you have Geargiarsenal, Redox and a random EARTH monster, you can set 2 Geargiarmor in your first turn (for a -1). Dark Hole is now cut from many competitive decks, so the 2 Armors set would be scary as fuck. And you can always discard Nishipachi to summon it, trigger the effecr to flip Arnor and all the madness begins. 3000 DEF is respectable too, at least Abyssgaios won't be getting over it

YGO will be very fun (but fast) after these things (and the baby versions) are released. However, the Dragon deck and Prophecy are real pain in our ass. It's simple as 2 best decks and a million good decks, which is a good part for the format. You'll need to make meta calls, finding random tech cards and such. Personally I'd prefer this to the all-Mermail format. Facing 1 deck in a whole tournament is no fun at all

Until next time ;)
