Sundial of the infinite interactions

Asked by Monomanamaniac 4 years ago

So according to Sundial of the Infinite the until and of turn portion of abilities ends, though the ability itself does not, so it is a easily abusable card. Recently I ran across a copy of the new neheb, Neheb, Dreadhorde Champion , and started wondering, does this work. Would the until end of turn portion of his ability and and makemy mana not empty as long as I doing have an and phase

No, your mana pool would still empty at the end of your turn. The wording you are concerned with means that all effects that last until "end of turn" end.

From the Gatherer: 9/22/2011: 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) All attacking and blocking creatures are 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. The cleanup step happens in its entirety.

Basically, what Sundial of the Infinite's ability does is skip your turn directly to the clean up step.

The end phase of a turn consists of the end step and the cleanup step. During the cleanup step, you discard down to your max hand size, then all damage and "until end of turn" effects wear off.

Comprehensive Rules for the Cleanup Step: 514.1. First, if the active player’s hand contains more cards than their maximum hand size (normally seven), they discard enough cards to reduce their hand size to that number. This turn-based action doesn’t use the stack.

514.2. Second, the following actions happen simultaneously: all damage marked on permanents (including phased-out permanents) is removed and all “until end of turn” and “this turn” effects end. This turn-based action doesn’t use the stack.

What you are probably thinking of is that Sundial of the Infinite can get rid of and prevent triggered abilities that trigger at the beginning of your end step. The "until end of turn" effect of the mana provided by Neheb, Dreadhorde Champion is not a triggered ability.

That's not what Sundial means when it says "'until end of turn' effects end". It means anything with a duration that lasts "until end of turn" will end immediately when you use Sundial to end the turn. In your example, ending the turn with Sundial of the Infinite will make the "you don't lose this mana as steps and phases end" ability end immediately. The mana will go away.

What I don't think you guys are considering is that the end step of your turn is skipped, you don't have an end step with this.

dragonstryke58 already gave the details, but here they are again: The End Phase has two steps - the end step and the cleanup step. When you use an effect like Sundial of the Infinite or Time Stop to end the turn, the game skips straight to the beginning of the cleanup step. Effects that last "until end of turn" or "this turn" wear off at the beginning of the cleanup step, meaning the last ability on Neheb, Dreadhorde Champion ends. The mana won't stay in your pool after the cleanup step ends.
