I LIKE this! I keep hearing about the "Tiny Leaders" format which is a new way to play EDH smaller and faster, and this would be a sweet general for that format. I actually think I'll brew with this today and put the deck list up on Gathering Magic next week if you're into that sort of thing.
The ceiling on this is relatively low, but I think this has a lot of potential. Then again, so did Exava, Rakdos Blood Witch. I don't have pricing data for this yet, but I'm not bullish at any price. Foils will be cheap and I might snag one to build around, but I don't think Tiny Leaders will ever skew prices unless the format ends up solved and staples mean each person has 3 or 4 personal copies of each staple. I can't see that happening.
