Skyshroud Troll

The whole design lives in the regeneration cost, with the body priced low enough that the shield is the point. A 3/3 for four mana sits below the green curve even by the standards of its era, but a renewable regeneration cost turns it into a creature that refuses to die to combat or to a single point-removal spell, and against a deck leaning on cheap removal it buys real tempo. Regeneration was green and black's signature toughness mechanic in this period, the color-pie answer to "how do you make a creature stick without giving it more power," and this card states the idea in its plainest form: no evasion, no static upside, just a body that costs the opponent more than one card to clear. The discipline is folded into the keyword itself: regeneration does nothing against exile, sacrifice, or bounce, and every activation taxes your mana on exactly the turns you most want to be developing. It is built for grinding board stalls, where the regeneration cost is cheap insurance and the opponent runs out of clean answers before you run out of green mana.
