Raging Minotaur

Haste is the entire lesson here. The Portal sets were built to teach combat to brand-new players, and this 3/3 exists to show one rule in isolation: some creatures can swing the turn they hit the table. There is nothing else on the text box because nothing else was wanted. The Minotaur Berserker typing is the era's flavor shorthand for "this one charges in," and the body is priced a full mana above where a competitive 3/3 with haste would sit, since these cards were never tuned against the main game. They were tuned against a kitchen-table opponent learning to block. Reading it as a constructed card misses the point; it was meant to be exciting to cast, not efficient to evaluate. Treat it as an artifact of design intent, a piece of the on-ramp Wizards built to widen the game's audience rather than to feed its competitive metagame.
