Hulking Raptor

The body is the giveaway that this is a four-drop pretending to be a two-drop. A 5/3 with Ward for four mana is already a fair-but-pushed beater, but the mana ability is what makes the cost work backward: it pays you at the start of your first main phase, every turn it survives, before you cast anything. That is the entire pitch. The card is designed as a ramp piece wearing an aggressive body, and what balances the engine is the timing window: the mana only arrives in your first main phase, so you cannot float it into an opponent's turn for instant-speed plays, and you have to keep the Dinosaur alive to keep collecting. Ward is the protection that lets the engine compound, taxing the cheap removal that would otherwise one-for-one a fragile three-toughness creature off the board before it ever pays for itself. So you get a creature that closes games and accelerates into the rest of your hand in the same slot, with the friction sitting squarely on the toughness: it ramps hard if it lives, and three toughness is the number that decides whether it does.
