Help me with this spell copy interaction
Help me brain. I have on my board a [[Mica, Reader of Ruins]], [[Twinning Staff]] and a random artifact. I have in my hand a [[Fireball]] or a random burn spell and a [[Reverberate]].
I caste Fireball, choosing not to copy it using it Mica’s ability. Holding priority, I caste Reverberate targeting Fireball, choosing to copy it using Mica’s ability and I’ll net one copy of Reverberate from staff. Is this an infinite loop of copied Reverberate and burn spell?
