Sunbird Standard // Sunbird Effigy

Most double-faced permanents flip on a fixed trigger or a paid cost that leaves the rest of the board untouched. Craft inverts that economy: the transformation devours permanents and graveyard cards as fuel, and the color spread of what you feed it becomes the payoff. A three-mana rock that taps for any color is honest fixing on the front, asking nothing but a slot. Assemble the Bird Construct from a mono-color pile and you get a 1/1 that produces a single mana; feed it a five-color junkyard and you land a 5/5 flier with vigilance and haste that adds all five colors at once. The body and the mana output read off the same exile pile and land on the same number, so the whole thing scales with how wide and greedy your board has already grown. Because craft only happens as a sorcery, you commit the material on your own turn, in the open, and the opponent sees exactly how large the creature you paid for is before it can swing. That timing is the counterweight to a mechanic that would otherwise be a blowout: no instant-speed ambush, no hidden information, just resources spent visibly for a body sized to your commitment. The strategic wrinkle is that it treats your own permanents and graveyard as raw material rather than assets to defend, rewarding the player who has already sprawled across colors and now wants to cash that sprawl in.
