I would imagine that this deck works just as well with any kinds of dragon!
Purple, Bone, Devonian, and Black Dragons can be switched for Emerald and the pillars and mark switched accordingly, and the deck would function just as well.
With Crimson Dragons, I'd imagine it to be actually better.
And it would work, but it would probably perform worse, with the rest of the dragons (except Phase Dragon. That deck's just mono-Aether, which tops all the rest
)
Great job on this one. I heard how successful this was in the tourney. Won a couple of times between 2 different people.
