A 5/5 for four mana is a body the color of red almost never gets to keep clean, and the rider explains the discount: this Dinosaur can't attack or block alone. That single clause turns a premium stat line into a creature with a partner requirement baked into its rules text. Going wide makes it free, since any second attacker unlocks the swing, but on an empty board it stands inert, a brick that can't even hold the fort by itself. The drawback cuts hardest exactly when you're most exposed: top-deck it into a fresh game with no other bodies and it does nothing, while the same card thrown onto a developed board is just a 5/5 beater at a steep rate. It's the "can't act alone" template that designers reach for when they want to reward board presence without leaning on a tribal or sacrifice payoff: the constraint is purely numeric, a check on whether you have a second creature, and it pays out the moment you do. No counters, no enters-the-battlefield trigger, no toolbox; the entire negotiation is between its size and that lonely-creature clause. Built for decks that flood the board early, it punishes the empty hand and rewards the full one, which is a cleaner way of saying it's good when you're ahead and useless when you're behind.
