Sorry to make 2 pages on this from my omni question since needed help with deck. With omni show...he plays SnT. He lays omni and I lay glimmer, bog or titan. He has priority since active player and no EBT but I have EBT. He can only play instants before my trigger or respond to my trigger on the stack. So he can play something from sneak attack since he has priority if free red mana. If not my trigger would be on stack next so priority passes to me. I then can leave it on the stack and cast grip on a target of my choice. Is this correct?
