Ob Nixilis, the Hate-Twisted

A punisher planeswalker built to turn an opponent's own engine into a clock. The triggered ability fires on every card an opponent draws, including their draw for the turn during the draw step, dealing one damage each time; the more they draw, the faster the counter runs. Cantrips, wheels, greedy card-advantage engines: all of it becomes a liability. Because it deals damage rather than draining life, damage-prevention and certain replacement effects can interfere, but under normal circumstances the passive clock is the primary win condition. The minus is where the design turns genuinely subversive. Most removal stapled to a walker is a clean two-for-one; here the compensation you hand the opponent (two cards) is precisely the resource the draw trigger punishes. Kill their creature, they draw two, they take two, and the "drawback" line becomes the reason to activate. That symmetry is the architecture: the two halves are limp apart and vicious together, since the minus manufactures exactly the triggers the passive wants. It rewards a shell already sitting behind taxing effects and forced draws, where loyalty is fuel rather than a grind engine. The loyalty math is the check: the minus costs two off a starting five, so the removal is a rationed resource and the card leans on the passive to close, not the ability. Black's punisher philosophy runs through the whole piece: offer the opponent a benefit, then make that benefit the trap.
