Priority

[JaCe BeLeReN]

If my opponent {Show and Tell}s in. {Omniscience}, can I once it resolves {Krosan Grip} the {Omniscience} before they play anything with it?

I'm not sure, after it resolves, they would have priority first, then maybe they would get the chance to cast one spell before you could krosan grip. After that because yours is split second they wouldn't be able to respond to it and play more spells.

You can {Krosan Grip} before anything is cast because of Split Second.

But the guy with omniscience has priority he could cast as many spells as he wants before passing priority

Instants only.

Awesome. Thanks guys.

Or 1 sorcery, enchantment, planeswalker or creature then as many instants as he wants

22 seconds

Oh so when a spell is cast, the active player who has priority can cast another without having to pass priority? I spose that make sense, if they don't want to cast anything then priority is passed.
