A Feather of the Phoenix has been working well, especially when I can recycle Confiscation, Pot of Avarice or Graceful Charity with it.

I've actually been using Recycle in the Deck too (put the Normal Magic Cards back into my Deck for later use)

D-Hero decks can be considered "control" right? Since they control what the opponent can and can't do in the subsequent turns...

I guess you could in some ways...at least for Dread Guy/"master" with making your D. Hero's unable to die in battle or destroyed at all (though, just "destroyed") and Diamond Guy/"Dude" with the opponent unable to negate the Normal Magic Card sent by Diamond Guy/"Dude's" effect.

I would consider most of the D-Heroes control monsters. The main thread of the D-Hero deck is controlling what you and your opponent will be doing in future turns.

Recycle is an interesting thought, I'll have to consider it more.

Which is basically the whole theme for season 2 of GX...all talk about "destiny" and "fate" and such.
