Awesome. Pure awesome. Any deck that can win off a completely underused (and hilarious!) card like Warp World deserves all the +s I can give it (ie, 1)

Sadly sideboarding is not really something I know much about so i can't really help you there..

Many thanks.
My biggest concern right now (I think - need to actually face it) is R/G Urzatron. While in theory I can ramp at least just as hard as it, a well placed Pyroclasm can really hurt. Also, of the decks out there, I see it as somewhat-less vulnerable to Warp World , especially if they're packing a full set (all three) of Eldrazi. Wouldn't stop me from doing it anyway.
