Flopsie, Bumi's Buddy (TLA)

Legendary Creature — Ape Goat

When Flopsie enters, put a +1/+1 counter on each creature you control. Each creature you control with power 4 or greater can't be blocked by more than one creature.

Niche lord for go-wide green strategies, but the evasion clause requires a critical mass of 4+ power creatures that most decks struggle to assemble consistently. The enter trigger is modest, and the mana cost is steep for what amounts to a conditional anthem in a format where more efficient lords and evasion effects exist.
