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.
Flopsie is a mono-green beatdown commander that dumps fat creatures, pumps your board with a counter wave, and pushes damage through by making your 4+ power threats nearly impossible to gang-block. You ramp into a wide-but-tall board, then alpha strike with creatures that demand single-blocker treatment.
Anthem-style counter dump on entry rewards going wide before casting it
Evasion-lite ability makes large creatures connect for commander damage and trample value
Mono-green gives access to the best ramp and the biggest fatties
Synergizes naturally with +1/+1 counter and trample payoffs
Six mana for an effect that does little if your board is empty
No card advantage or recursion built into the commander
Vulnerable to board wipes since the strategy is creature-centric
The 'one blocker' clause does nothing against go-wide token chump defenses if creatures lack trample
