Glorious End

Though other spells and abilities that are exiled won’t get a chance to resolve, they don’t count as being countered.

Any “at the beginning of the next end step” triggered abilities won’t get the chance to trigger that turn because the end step is skipped. Those abilities will trigger at the beginning of the end step of the next turn.

If any triggered abilities do trigger during this process, they’re put onto the stack during the cleanup step. If this happens, players will have a chance to cast spells and activate abilities, then there will be another cleanup step before the turn is over.

If Glorious End’s delayed triggered ability is countered, it won’t trigger again. The same is true if it’s removed from the stack in any other way (such as by a second even more Glorious End) or if it resolves and you don’t lose the game (perhaps because of the emblem of Gideon of the Trials).

Ending the turn this way means the following things happen in order: 1) All spells and abilities on the stack are exiled. This includes spells and abilities that can’t be countered. 2) If there are any attacking and blocking creatures, they’re removed from combat. 3) State-based actions are checked. No player gets priority, and no triggered abilities are put onto the stack. 4) The current phase and/or step ends. The game skips straight to the cleanup step. 5) The cleanup step happens in its entirety.
