Hulking Goblin

The drawback is the entire card: a 2/2 attacker that surrendered its ability to play defense and got nothing in return. That trade tells you everything about the design brief behind it. The Portal sets stripped Magic to a beginner-legible subset, and one job of that subset was to demonstrate that a creature's stat line has two sides: it can attack, and it can block, and those are separate things a card can give or take away. Most drawback creatures attach a downside to a juiced-up rate, justifying the restriction with extra power, a bigger body, or evasion. This one prices the forgetting as if it were free, because the lesson mattered more than the bargain. For a new player learning that combat has a back side, a body that does one thing wrong is a clean illustration: it walks into your blockers, it cannot stop theirs, and the rules-text clause that causes that is sitting right there in plain language. There is a quiet honesty in how little it asks for. It does not pretend the inability to block buys anything; it simply is a small red creature that attacks and only attacks, the back half of a stat line carved away and presented as a teaching example rather than a competitive proposition.
