I actually managed to deck out eternal crusader using just a normal deck earlier...if had nearly all its creatures quinted, drew through it's cards extremely quickly, and also on the last turn, animated its weapon meaning that one couldn't use its ability
I like this deck because it also fairs well against other False Gods. I managed to almost deck out Destiny (I was dissapointed when I won the regular way, he was down to 6 cards!!!), and (in case your wondering) I choose decking out over a regular win because deck out always gets an elemental mastery once you've got enough shards out
I'm also considering adding in some deflags to destroy some of the FG's permanents (they usually supply the quanta)
