The payoff that the Spiritcraft archetype was always building toward, and the one that asks the most of it. Where most of the spell-matters Spirits of its era rewarded you with a one-shot effect (a damage trigger, a tempo bounce, a scry), this one banks every cast into a permanent +1/+1 counter on a creature of your choosing. The distinction matters: nothing here decays at end of turn, so a chain of cheap Spirit and Arcane spells stacks into a real threat rather than a flickering burst. The targeting clause is doing quiet work too. Because each counter lands on any creature you point at, you can pile the whole game's worth of growth onto a single evasive body or spread it to keep a board of small Spirits relevant against a sweeper-light opponent. The cost is that the engine sits at the top of a counters-and-Arcane curve and contributes nothing the turn it lands: it is a fifth-turn investment that only pays once you have already committed to casting Spirit and Arcane spells in volume, and a 3/3 with no built-in protection is an obvious removal magnet before the engine ever turns over. That fragility is the honest price of an open-ended, recurring counter generator. Within the splice-and-Arcane shell it was built for, it converts your spell count directly into board presence; outside that shell, it is a 3/3 waiting for a trigger that never comes.
