Zhao, Ruthless Admiral
The two halves of this card point at different engines but converge on the same attack step. Firebending 2 dumps into your pool the moment it attacks, and because that mana surfaces mid-combat and empties at end of combat, it reads as ramp but works as a combat subsidy: red to spend on a firebreathing pump, an instant-speed trick, or any activated ability that matters while the swing is already declared. That half asks nothing of your deck's composition; every attack pays out two red regardless of what else you're doing. The sacrifice trigger is the half that wants a specific shell around it, a black-red aristocrats build where permanents leave under your own control for value. Stack enough outlets and the +1/+0 to your whole board becomes an incremental overrun, each Treasure cracked or creature fed pushing another point across the swing. What connects the two is tempo rather than card advantage. This is a card built for a decisive attack step where mana appears, permanents die on command, and the team hits harder than the board state suggests it should. A 3/4 is durable enough to lead the charge and trade up, but it taps to attack and has no vigilance, so it commits to offense rather than holding back to defend. The Firebending gives it a floor in any aggressive black-red deck; the sacrifice trigger is what rewards building the aristocrats engine underneath it.
