Scuttling Butler

A 4/1 body is a coin flip: it hits like a real threat and dies to anything that so much as looks at it, and pairing that fragility with conditional double strike is a deliberate bet on tempo over durability. The trigger checks for two or more multicolored permanents, not two colors of mana, which steers it toward decks that already run gold cards as a matter of course rather than any tribe or artifact theme. When it turns on, the math is brutal: four power with double strike reads as eight, delivered by a creature that will not survive the swing back, so it belongs in the attack step and the trade, not tucked behind blockers. The combat-step timing is the quiet knob. The condition is evaluated at the beginning of combat on your turn, so a multicolored permanent that leaves before then, or arrives after, never counts, and an opponent holding removal can strip the enabler in response to shrink the attack down to a bare 4/1. That makes it a construct scaling with your commitment to a gold-heavy build: a cheap, punchy beater for a deck already leaning on multicolored permanents for reasons that have nothing to do with this creature.
