Uhm....One problem here.
You'll flip your deck upside down, be left without a library, they'll etb and you draw a card and deck yourself.
So...might want to pull them out. =)
you can stop at anytime though, its a may ability, you stop when you hit behemoth and vengence then kill right there! theres a small chance of it happening but still its worth it! lol
Lose some lands. Maybe get in a few Soul of the Harvest
And it'll be hard casting phantasmal image, it would be better to use Phyrexian Metamorph instead. Gotta love phyrexian mana
I don't think that Phantasmal Image is worth the blue mana.
