Murderous Betrayal card art
Murderous Betrayal is a repeatable, unconditional creature removal engine — it kills anything for half your life total, as many times as you can pay. In a life-gain deck or a Commander shell that treats life as a resource, that cost becomes trivially manageable; everywhere else, it will kill you faster than your opponents will.

Commander is the natural home for Murderous Betrayal — life totals start at 40, life-gain synergies are abundant, and unconditional repeatable removal is worth a steep cost in a format where one creature can take over the game. In Legacy and Vintage, cheaper instant-speed options like Swords to Plowshares exist at no life cost, so Murderous Betrayal never makes the cut in competitive lists. Modern has similarly better options and 20-life starting totals that make the halving cost genuinely dangerous. Oathbreaker follows Commander's logic closely enough that the card is playable there in the right shell, particularly with a life-gain signature spell.
