Well theres still time for things to change but I'd be shocked if there wasn't at least 1 refess in the top 20 this time (heck at least top 10). Their low level strats still don't seem up to snuff but their high level strats seem to be able to go toe to toe with any other strat in the game right now. I'd be running a high level refess build myself (I still occasionally do run refess, its just not my best deck) but I lack the cards necessary to make it top tier competitive (despite getting around 4 boxes of set 2 -_- darn you coatl and judgement hammer).
Yes, high levels may be the only strat people have found that works for them, but again, atleast they have something that works! They didn't seem to have anything in set 1, and honestly most of the top Gowen decks, for instance, in set 1 were pretty similar as well.
The bunnies of Lavato have special abilities, like 'Action Skill: Make Carrot Disappear.'
