Target creature gets +3/+0 and gains lifelink until end of turn. Regenerate it. (Damage dealt by a creature with lifelink also causes its controller to gain that much life.)

Renown 1 (When this creature deals combat damage to a player, if it isn't renowned, put a +1/+1 counter on it and it becomes renowned.)

: Regenerate Undercity Troll. (The next time this creature would be destroyed this turn, instead tap it, remove it from combat, and heal all damage on it.)
