Tackle Artist
Opus reframes the spellslinger payoff as a growth engine rather than a burst reward: each instant or sorcery adds to this body over time, and the second clause is where the math earns its keep. Most spell-count creatures treat all your casts equally, which pushes a deck toward cheap cantrips fired in volume. Here the counter arithmetic bends toward expensive spells: reach the five-mana threshold on a single cast and you get two counters, quietly steering the archetype away from a rain of one-drops and toward fewer, heavier spells that swing the board and the clock in the same breath. Trample is the delivery mechanism, not filler. A body that scales this fast outgrows chump blockers within a turn or two, so trample converts each new counter into damage that gets through rather than damage that gets soaked. The trigger fires on the cast, not the resolution, so it grows even when the spell itself is countered, and firing at instant speed off your instants means it can arrive mid-combat larger than the attack step began. The tension is real: the card wants a pilot committed to casting spells but rewards casting the ones an opponent least wants to walk into, asking you to build around expensive interaction instead of around sheer count.
