Leatherhead enters with a hexproof counter on her.
Whenever Leatherhead deals combat damage to a player, you may remove a counter from her. When you do, destroy target artifact or enchantment that player controls.
Suit up Leatherhead as a mono-green beater, connect for combat damage, and grind down opponents' artifacts and enchantments while smashing in for big trample damage. She enters protected by a hexproof counter, so lean into proliferate and counter synergies to keep her hexproof while also fueling repeated destruction. You win by buffing her into a lethal voltron threat or going wide with green creatures.
Built-in hexproof counter makes her resilient to targeted removal early
Trample plus green ramp lets her hit hard and push damage through blockers
Doubles as repeatable artifact/enchantment removal, rare in mono-green
Counter-based protection synergizes with proliferate and +1/+1 counter themes
Removal effect only triggers on combat damage to a player, so she must connect
Once the hexproof counter is removed she's vulnerable to spot removal
Mono-green lacks card draw, interaction, and evasion outside of trample
Board wipes and chump-blocking strategies blunt her voltron plan
Vulnerable to flyers and reach creatures stonewalling her attacks
