The drawback here is the whole point: a 4/3 for four in red is a fine rate, and the cost of that rate is that you surrender control of your attack step whenever this swings. Forcing all your creatures to attack is a real liability, not flavor text. Every creature that is able to attack must, the moment this one commits: mana dorks you wanted to leave home, blockers you were holding back, anything you would rather have kept on defense. Creatures that came down this turn are off the hook only because summoning sickness means they cannot attack at all, which is the one quiet exception the "if able" clause carves out. The constraint is sharper than it looks because of how the requirement resolves. This is a triggered ability that goes on the stack, so it triggers when this attacks and can be responded to; once it resolves it simply restricts how you declare attackers. When you choose to send this creature in, the rest of your eligible team is locked into the same declaration, with no chance to pull the dork back once the beater is committed. You either build a board that wants every creature in the red zone every turn, or you accept that this body occasionally walks your support creatures into bad trades. That binary is the design statement. It sits in red's small lineage of attack-coercion effects where the friction lands on your own side of the table, and it refuses to be a flexible midrange body, which is exactly why a clean 4/3 for four still carries a downside line at all.
