Let's say I have a {Spell Queller} on the field and exiled under it I have a {Thoughtseize}. During combat my opponent goes to {Lightning Bolt} the Queller and I respond with a {Restoration Angel} blinking the Queller and exiling the bolt. Would they be able to cast that seize during combat at instant speed?
Another senario that happened that I was unsure about, was my opponent cast {lightning Bolt} And I cast the queller and exiled it. He then overloaded {Cyclonic Rift} on me bringing it back to my hand. Could I have cast him again and exiled the bolt again? I was at three life, and I am pretty sure I was able to, but I didn't know the priority timing...
1st part
From gatherer
If the player casts the exiled card, he or she does so as part of the resolution of Spell Queller's last ability. The player can't wait to cast it later in the turn. Timing permissions based on the card's type are ignored, but other restrictions (such as "Cast [this card] only during combat") are not.
Second part
When your opponents spell returns to the stack, your spell queller will be in your hand and you may cast it again
Thanks dude, greatly appreciated on the answer
