Obeka, Brute Chronologist

Ending the turn is one of the strangest levers Magic hands a player, and this ogre puts it on a repeatable, untap-gated button. The ability lets the player whose turn it is choose to end that turn early: the stack empties, "until end of turn" effects die, damage wears off, and the game jumps straight to cleanup. The color identity is the tell. This is not a defensive tool but a self-serving combo enabler, and the key word is "may": only the active player decides, so on your own turn you can cut off a triggered ability, a mandatory draw step, or a "must sacrifice at end of turn" clause before it catches up to you. Cards that impose an escalating cost or a delayed penalty become one-sided when you can simply refuse to let the turn finish paying for them. Note the bluntness, though: ending the turn clears the entire stack at once and skips whatever is left of your own turn too, so it wipes everything rather than surgically answering a single trigger, and sequencing matters. The 3/4 frame barely registers next to what you are actually buying: the power to treat "end of turn" as a resource you negotiate instead of a fixed checkpoint. That inversion, turning the turn's cleanup from a certainty into a lever, defines the card, and it rewards a build that deliberately loads the endgame with penalties only its own turn can dodge.
