Partner with Rocksteady, Mutant Marauder (When this creature enters, target player may put Rocksteady into their hand from their library, then shuffle.)
Deathtouch
Whenever Bebop deals combat damage to a player, you may draw X cards, where X is the number of counters on Bebop. If you do, you lose X life.
Bebop is a mono-black counter-matters Voltron beater: pile +1/+1 counters onto a deathtouch body, connect for combat damage, then refill your hand by drawing X cards (paying life) every turn. You curve into counter enablers and evasion, grind through removal with reanimation and protection, and convert your card advantage into a lethal swing or a black finisher.
Deathtouch makes Bebop a fearless attacker and blocker that trades up against anything
Repeatable card draw scaling with counters keeps your hand stocked in mono-black, a color hungry for advantage
Cheap two-mana commander that comes down early and snowballs with proliferate and counter doublers
Partner with Rocksteady gives flexible deckbuilding and a free tutor-to-hand on a stick
Card draw costs life, so racing aggressive decks or paying for it under pressure can kill you
Needs Bebop to connect — gets walled by go-wide blockers, fog, or evasion answers
Mono-black struggles to interact with the stack and lacks artifact/enchantment removal
All-in on the commander; removal-heavy tables can tax you with repeated recast costs
