This had been noted before, but it has been a while and was in a thread about multiple issues:
Azor can still use his loyalty abilities with Immortal Sun on the board. This occurs when either Azor plays it or I play it, and then one is destroyed. I am not able to activate my abilities, and he can use his abilities until i replay the Immortal Sun.
Wait, is this Azor or Azor’s Gateway? Because I have never seen Azor use an ability with the Immortal Sun out (that I noticed, at least), but I have heard people say that Azor’s Gateway nuked them even though they had an Immortal Sun out (I haven’t personally seen it because after they said this I didn’t want to risk it)
This actually works either way. I have had a match where both Azor and I have Immortal Sun in play. Azor exiled mine, then my Teferi was able to bring out his ult while Azor is doing nothing with 30 loyalty.
This is rarely noticed asmost of the times it’s the player doing the removal.
