Thousand Year Storm Infinite Loop
Asked by chosenone124 5 years ago
My opponent casts Radical Idea with Thousand-Year Storm out. In response to the storm trigger, they cast Expansion. I cast Sinister Sabotage on Radical Idea. Does the game enter an infinite loop since the only legal target for Expansion is other Expansions?
No. Both Thousand-Year Storm and Expansion give the option to choose new targets, but do not require it. Your opponent has the option to leave the target unchanged, which will allow the stack to clear, breaking the loop.

To be clear, the stack is as follows: Radical Idea, Thousand Year Storm trigger, Expansion, Thousand Year Storm trigger, Sinister Sabotage targetting Radical Idea.
