Esoteric (Whenever you cast a spell of mana value greater than the number of Lore counters on this creature, it gains a Lore counter.)
At the beginning of your endstep, Smoke Shaman deals X damage to any target, where X is the number of Lore counters Smoke Shaman gained this turn.
See Forgotten Ancient Ways. Not even sure what I meant with (this use of the word) Esoteric's original reminder text. At least this wording is clear, if boring.
