For this event, we want as little cards in one deck as possible, so we don't lose too many cards in one game. That deck works theoretically, but can be out rushed if can't be set up quickly. It's also vulnerable to mass creature control combined with permanent control.
Frogtal can be a bit problematic, because the frogs need to be upped to do some real damage and aether towers are needed to use the fractals early. How many upped cards can a master use?
Adrenaline vampire is a solid deck, super speed rush plus quick healing, almost too good to be true, I don't have much experience using it though.
The light/life deck should be reserved for a fighter I think, because it works just as well unupped.
And I don't understand why the nymph's tears in the growth deck is needed, I think replacing them with squids would work better.
Did anyone notice all three fighters have used/using the jade dragon as avatar.
