Simic Ascendancy

An alternate win condition priced like a durability spell, and the trick is that it never counts creatures: it counts counters. The distinction matters enormously. This does not ask you to keep twenty power on the board, where a single wrath resets the clock. It asks you to have placed twenty +1/+1 counters on your creatures over the course of the game, and every one of those placements banks an equal number of growth counters here, where a board wipe cannot touch them. That decoupling of the tally from the battlefield is the whole design conceit: the +1/+1 counters live and die on your creatures, but the growth counters they mint stay put. You can lose the creatures, lose the board, lose the race in every conventional sense, and the count keeps climbing every time a fresh counter lands on something you control. The two-mana enchantment slot is cheap enough to deploy early and let it accumulate passively off counters you were adding anyway, and its own pump ability offers a floor when nothing else is placing them. Any effect that adds +1/+1 counters in bulk, or that proliferates them, drives the count toward twenty far faster than the printed activation suggests. Its exposure runs the other way: the enchantment has no protection and must survive to your upkeep to cash out, so an opponent who reads the clock has a window to break the engine before it fires. What it demands in return is a deck built to generate counters as a byproduct of its normal game rather than a combo assembled around it.
