The Top 5 decks of the next format I predict will be in the following order:
1. Mermail
2. Prophecy
3. Verz
4. Incarnate Dragons
5. Fire Fist
Mermails are a very good deck that top everything in TCG and OCG, whether it be Pure or the Undine engine. Mermails are a dominating force that I feel will begin winning YCS and more Regionals.
Prophecy are beginning to Top in the TCG and already have Spellbook Judgment Day in OCG and are topping there as well, sometimes winning. It is predicted they will be Tier 1 due to how the build is with Spellbook Judgment Day in the deck.
Verz are dominating a lot of tournaments in the OCG, mainly Verz Rabbit. They are somewhat easy to side against, but are very very good. I feel they will do a lot in TCg once Hidden Arsenal 7 comes out.
Incarnate Dragons....all I wanna say is I thought I was going to legit flip my laptop playing against them on DN and Dev Pro. They are extremely good, beyond better than Chaos Dragons. They will do a lot this coming format in my opinion once they are released.
Finally, Fire fist. fire Fist have been doing what Mermails did when they came out, topping a lot of Regionals and topping YCS. I feel they will continue to perform very well against most decks, but there are cards that screw them over. However, I feel they will be a deck to be wary about.
