Tribal Unity

Scalable tribal anthems are usually permanents, but this one collapses the whole effect into a single instant-speed burst, which changes what the spell is for. A standing lord like Goblin King taxes a slot and a clock; here you pay X once and dump the entire pump into one attack or one block, then it's gone. The result is a combat play disguised as a tribal payoff: in a board stall between two creature types, holding it open turns a doomed alpha strike into a lethal one, or a profitless block into a two-for-one. The creature-type clause is broader than a costed lord wants to be, since you name the type as the spell resolves rather than building it into a static ability, so it scales with whatever tribe your board happens to be and can even buff an opponent's creatures if you ever want to (you won't). It comes out of an era when tribal synergy moved to the center of constructed and Limited design, and the question it answers is the one those decks kept asking: how do you reward a wide creature-type board without committing another body to it. The tension is that X scaling makes it a dead card early and an overwhelming one late, with no floor between those two states; you are paying full price for a one-turn window and betting the game on hitting it.
