Gravelgill Duo

The single hybrid pip lets the card slot into either half of the dimir pairing, but the body underneath only pays off when you commit to both colors. The two triggers split cleanly along that line and reward opposite plans. A blue spell pumps it, turning a fragile 2/1 into a beater that grows with every cantrip or counterspell. A black spell hands it fear, threatening to push damage past a clogged board. Neither fires on a turn you hold up mana and cast nothing, so this is a tempo creature that wants you actively spending in its colors rather than a passive lord sitting on the battlefield. The real reward lives in the overlap: cast a blue spell and a black spell in the same turn and you get a 3/2 with fear, the kind of swingy, color-pair-matters payoff this style of design traded on in its era. A deck splashing one color for a single spell gets a strictly worse version than one built down the middle. That conditional reward is a deliberate cost levied on a small, easily killed body, and it is what turns the Duo into a deckbuilding question instead of a fixed stat line.
