I have a question; if you tap Magosi once for an eon counter, then you untap it, and tap it again using another card's effect in the same turn, will you be skipping one turn, or two?

I think you misread it. He said that his deck would destroy a mono black, but a Lotus Cobra would be troublesome for the B/W Vamp Deck.

I like it. The creatures are pretty fast, annoying, and the damage adds up. I'm guessing sleep is there so you don't leave yourself wide open after a big rush?

Kamahl, Fist of Krosa and Garruk both give overrun-like effects, but if you can pull off the infinite loop of squirrel tokens, would you really need overrun?

It's pointless to use a 0/1 flier when you don't have any cards that can pump it.

Does this actually work though? Helix Pinnacle has shroud, so you can't target it with Gilder Bairn, can you?

Yeah, you should definitely add another win condition or two. It's not too easy to win quick enough if you're relying on three venoms to kill an opponent.

I'm pretty sure you can only have 4 of each nonbasic land in a deck.
