Stall Staff (Budget)

5 total creatures in the game: 4 ornithopters and 1 progenitus. use the staff to keep switching creatures unit progenitus comes out to take the win! if a progenitus is drawn already, allow the ornithopter to die, and use the deathrender to bring the progenitus from your hand to play. there must however be a creature on board to search for progenitus - simply play ornithopter and use the staffs ability in 1 turn (which only costs 3 mana). dont have enuf blockers for a big attack? use nuisance engine to produce some blockers, along with stalking stones, and chimeric eggs. budget is 30 bucks!
