Uthden Troll

A 2/2 body for three mana, deliberately under-rate even by Alpha standards, with the regenerate activation priced as the entire value proposition. The design logic is a defensive tax: opponents who want this dead in combat or to damage-based removal have to spend extra mana or an extra card, and the troll's controller holds up a single red as a soft shield through the midgame. The friction is that regenerate does nothing against exile, sacrifice, or destruction that prevents regeneration, and the 2/2 never grows into a threat the opponent must answer; you end up paying mana every turn to keep a clock that was already slow. Wizards walked away from the idea once the math became clear: a body that has to be paid for twice (once on cast, once per combat) tends to lose to a body that only costs once. The lineage shows up in later trolls (Sedge Troll, Troll Ascetic), each iteration tilting the dial toward either a better body or a cheaper shield, rather than splitting the difference and ending up under-rate on both ends.
