Actually, I believe there are a host of new cards which bring back cards outside of the game. Its now like bringing back from the graveyard (or so I'm told)!
Yeah, I had a 60 card deck with 12 lands and not a single non-artifact card. I'd muligan down to a "perfect" hand and would have won by tern 5 by smacking people arround with a 43/39 with flying, cannot be blocked by more than one creature, cannot be blocked by fewer than two creatures, cannot be the target of spells or activated abilities, double strike, first strike, tramble and some other nasty things. Normally they died before that. A 21/20 flier does just as well most of the time.
I had 3 DotV, but never used them. Didn't need to and I didn't own any Retrievers.
