Tilonalli's Knight

A common-rarity payoff built to give a Dinosaur deck a reason to keep a small threat on the board, sitting at the seam of two unrelated tribes: a Human Knight that cares about Dinosaurs, useful to neither type in isolation. The conditional pump is checked at attack, not at cast: the creature swings as an ordinary two-drop most of the time, and only grows in the turns when you actually control a Dinosaur to support it, which means the bonus comes online exactly when the tribal deck is functioning and goes dim the moment it isn't. That is the tension as a deckbuilding piece: it costs nothing in the abstract, but it pays nothing either until the rest of the synergy shows up, so it rewards committing to the type rather than splashing a Knight as filler. The attack-trigger framing is also what makes the bonus fragile rather than durable. Because the check happens on each declaration of attackers, the Dinosaur has to still be present at that exact moment; an opponent who kills it on your upkeep, or in response to your combat, strips the pump entirely. A version that stamped a permanent boost onto entry would stick regardless; this recurring conditional means the tribe has to survive to combat every turn, not just once. Plain in a vacuum, exactly as intended for a low-rarity enabler whose job is to reward the tribe rather than headline it.
