Temperamental Oozewagg
The Brushwagg subtype has always been a joke Wizards keeps reprinting for the bit, so folding it into an Ooze counters payload is a wink most players will miss and a design pivot most players will feel. The engine is the anthem clause. Counters, Equipment, and Auras all count as modifications, so any creature you touch with a buff also picks up trample, and the Ooze itself qualifies the moment its own adapt resolves. That reframes a self-pumping 4/4 with an activated adapt ability into a static payoff for a whole board of counters strategies, +1/+1 aggro, and Equipment shells that otherwise have to source trample creature by creature. The adapt cost is a one-shot investment, not a repeatable pump: once two +1/+1 counters are on it, the ability does nothing further unless something strips them off, which is the constraint that keeps a growing body from also being a mana sink you never stop feeding. What it resolves is the familiar dead end of go-wide counters decks: a stalled ground where fat, growing bodies get chumped forever while the counters pile up to no purpose. Handing the entire modified team trample converts that incremental growth into lethal math, and because the card modifies itself the instant it adapts, it never sits fully dead in a matchup where the rest of your buffs get answered.
