Hearthborn Battler

The trigger keys off any player's second spell each turn, and that "each turn" clause is doing more work than the body suggests. On your own turn, a low curve of one- and two-mana spells hits the second cast reliably and pings for two. But because the trigger isn't restricted to your turns, casting a pair of instants during an opponent's turn fires it there too, so a deck built to hold up cheap interaction can stack multiple two-point bursts across a single turn cycle. The trigger even fires on an opponent's own second spell, quietly taxing spell-dense mirrors from both sides of the table. What keeps the 2/3 body honest is the shape of the reward: the damage is aimed at an opponent rather than any target, so this is a reach piece and not a removal outlet, and only the second spell each turn triggers, not the third or fourth. Piling on extra spells past the second does nothing until the next turn resets the count. That points the card firmly at a deck that wants many cheap spells across many turns rather than one big play per turn, and it sits in the lineage of creatures that convert spell density into fixed direct damage, trading scalable payoffs for a flat, opponent-only two-point clock that starts the moment haste puts it down.
