Magic Ruling: By the Skin of Gideon’s Teeth
We are at 0 life.
However, we control Gideon of the Trials, having already activated his emblem ability, which states, “You get an emblem with ‘As long as you control a Gideon planeswalker, you can’t lose the game and your opponents can’t win the game.'”
We also have a Naturalize in our hand, which can destroy an artifact or enchantment at instant speed.
Our opponent casts Ixalan’s Binding, targeting our Gideon with the Binding’s enter-the-battlefield ability, “When Ixalan’s Binding enters the battlefield, exile target nonland permanent an opponent controls until Ixalan’s Binding leaves the battlefield.”
Do we lose the game?
The answer? Not yet we don’t!
Ixalan’s Binding’s ability is on the stack, so it will resolve no matter whether we Naturalize or not. So if we DO Naturalize, destroying the Binding, will its ability still exile Gideon before checking whether the Binding is still on the battlefield?
Luckily enough, there’s a rule for this!
- 610.3. Some one-shot effects cause an object to change zones “until” a specified event occurs. A second one-shot effect is created immediately after the specified event. This second one-shot effect returns the object to its previous zone.
- 610.3a If the specified event has already occurred when the initial one-shot effect would cause the object to change zones, the object doesn’t move.
So, because Ixalan’s Binding has already left the battlefield when its “until” ability is resolved, Ixalan will not bind Gideon based on these plays, and we survive by the skin of Gideon’s teeth!
