2 rulings from Wizards of the Coast
- 24 January 2020If Wings of Hubris becomes attached to a creature you don't control, you can activate the ability to make that creature unblockable, but you won't be able to sacrifice the creature at the beginning of the next end step.
- 24 January 2020If you gain control of a creature "until end of turn," you control it during your end step. If you use Wings of Hubris to make this creature fly too close to the sun, you'll sacrifice it.
