Fairgrounds Trumpeter

The trigger here is a payoff dressed as a creature: it does not care about combat or about its own counters directly, but about whether a +1/+1 counter landed on any permanent you control this turn. Grow a mana dork, resolve an adapt, put a counter on the Trumpeter itself, and at each end step this Elephant pockets one more. That one-counter-per-turn cap is what keeps it from spiraling, but it also reveals what the card is built for. It rewards counter density rather than counter size: the ideal shell is a wide board of permanents all ticking up incrementally, with the Trumpeter accruing steadily until it is quietly the largest body on the table by attrition. The 2/2 is a floor, not a stat line to build around. What earns it a slot is the breadth of the trigger condition. It does not ask the counter to come from a specific source, a creature, or a spell, only that a +1/+1 counter actually gets placed on a permanent you control. So it is agnostic about how the growth happens but strict about what grows: loyalty ticks and other counter types never feed it, and it must be a permanent under your control. A proliferate that finds an existing +1/+1 counter to multiply satisfies it; a proliferate with nothing to add to does not. The effect has to resolve into an actual counter, or the end step passes with nothing to catch.
