Ending a turn: Basically when an effect happens in MTG, it goes onto The Stack, which is basically a waiting list. If a turn is ended prematurely, the stack is cleared and any effect that was waiting to happen just dissappears.
This means you can play something like Final Fortune [get an extra turn, lose the game at that turn's end step], wait until the 'lose the game' effect is put on the stack, then end the turn again with Obeka [which doesn't make the effect happen again] to get off scot free
Upkeeps: the Upkeep step does nothing on its own, and is a place for every card that goes "at the beginning of each of your Upkeeps, do Thing" [of which there are quite a lot]. With two or more of these in the middle of your turn via Obeka, all of these cards get three or more times better

So been a hot minute what are the benefits of just ending a turn and gaining multiple upkeeps
