Sneak
Attacking Ninjas you control have deathtouch.
Whenever Dark Leo & Shredder deal combat damage to a player, create a 1/1 black Ninja creature token. Then if you control five or more Ninjas, that player loses half their life, rounded up.
You're a BW Ninja tribal aggro-combo deck that swings with evasive bodies, returns them to hand, and uses Sneak/ninjutsu to drop Dark Leo & Shredder onto the battlefield connecting for free. Every hit makes a Ninja token, snowballing your board toward the magic number of five Ninjas, at which point each commander connection halves an opponent's life total. With deathtouch on your attackers, you also dominate combat and force damage through.
Add unblockable/evasion enablers (Whispersilk Cloak, Cover of Darkness, Rogue's Passage) so the commander and Ninjas connect every turn, and token doublers to hit five Ninjas faster. Tighten the mana base with efficient BW dual lands, fast mana, and cheap protection like Swiftfoot Boots to keep the commander alive. Round out with strong tutors (Vampiric Tutor, Demonic Tutor) and a few aristocrat payoffs to convert excess tokens into a backup win when combat stalls.
