Flux Channeler

A cheap Wizard that turns your whole spell suite into a counter-multiplying engine. The trigger is the whole trick: instead of proliferate arriving as a single one-shot rider on an instant or sorcery, it fires on every noncreature spell you cast, so the counters you already care about compound across a turn rather than blinking up once and vanishing. A loyalty counter on a planeswalker, a +1/+1 on a growing threat, a charge counter on an artifact: each ticks up for free every time you were going to sling a cantrip, a removal spell, or a counterspell anyway. The 2/2 body is deliberately soft, fragile enough to die to almost anything, because the payoff already scales with a deck of triggers stacked behind it; give it evasion and durability too and the engine would run away with the game. Its lineage runs through the counter-doubling shells that ask for real setup, Doubling Season chief among them, but where those cost a full turn of mana or demand a build-around, this one just asks a spell-heavy blue deck to keep casting spells. The friction sits in the requirement for something worth multiplying: with no counters already in play, each trigger resolves and finds nothing to grow, which anchors the card as a support piece that amplifies an existing plan instead of starting one.
