Card Spotlight
A 4-mana Grixis Ogre whose only ability is "{T}: The player whose turn it is may end the turn." On your own turn, that erases end-step drawbacks like the loss clause on Final Fortune or the sacrifice on Sneak Attack.

As the commander, Obeka is a build-around rather than a value engine. Her ability needs {T}, so without haste she does nothing the turn she comes down, and a 3/4 body draws removal before she untaps. The deck exists to set up an end-step drawback and have her ready to cancel it.
In someone else's 99 she's a narrow include. She belongs only in a Grixis deck already running Final Fortune, Sneak Attack or similar cards, and Sundial of the Infinite does the same job on your own turn for {1} in any deck.
Final Fortune ↗
An extra turn for {R}{R}. Ending that turn before its end step, or in response to the trigger, removes the loss clause.
Sneak Attack ↗
Puts a creature onto the battlefield with haste. Ending the turn with the sacrifice trigger on the stack lets you keep it.
Kiki-Jiki, Mirror Breaker ↗
Each hasty token copy is sacrificed at the next end step unless Obeka ends the turn with that trigger on the stack, so the copies accumulate.
Sundial of the Infinite ↗
A second end-the-turn effect for your own turn, so the plan still works if Obeka is removed.
Obeka's original Commander Legends printing is inexpensive. She's worth picking up for the specific deck she leads, and not worth a slot anywhere else: buy her when you're building around end-step drawbacks, skip her otherwise.
Yes, for the specific deck she leads: Grixis cards with a drawback that happens at the end step. Ending your own turn skips the end step, and if a delayed trigger such as Final Fortune's loss clause is already on the stack, ending the turn exiles it. Without those cards she is a 3/4 for four mana that rarely matters.
Decks running extra-turn spells that make you lose at the end of the extra turn (Final Fortune, Last Chance), cards that give you a creature only until the end step (Sneak Attack, Kiki-Jiki, Mirror Breaker), and anything else that wants the turn to stop before the end step. She pays off a plan built around those cards. She is a poor reason to start one from scratch.
Only if that opponent agrees. The ability lets the player whose turn it is choose whether to end the turn, so on an opponent's turn the choice is theirs. In practice she does her work on your own turn.
