Warbreak Trumpeter

Morph priced as a doubler is a rare and clever trick. Face down for three mana, this is the same 2/2 that every morph creature presents, but the unmorph cost spends X twice while the payoff trigger pays X out only once: turn it face up for and seven Goblins fall out of the flip (eight bodies, counting the Trumpeter). The doubled cost is the brake on a payoff that would otherwise scale linearly with mana. A token generator that gave X for X would be flat and predictable, so the cost was bent to make the flip a real commitment: a big-mana payoff hiding under a one-drop's printed mana cost. The timing is where it gets subtle. Turning a morph face up is a special action that uses no priority window, so the flip itself cannot be answered; the resulting token trigger does go on the stack, and an opponent gets a chance to respond before the Goblins arrive. The wrinkle is that this window cuts against you on the unmorph: flipping in response to an announced sweeper just resolves the token trigger first, putting the fresh Goblins onto the battlefield in time to be swept away with everything else. As a Goblin tribal piece it sits oddly: most Goblins want to be cheap and forward, while this one wants to sandbag mana and go long, a slow engine wearing the wrong creature type.
