Does Isochron Scepter and Extirpate work?

[GGoober]

One of my friend mentioned that there's a ruling that extirpate on a scepter might not work due to split second rules. Just wanted to check on this if anyone has any rule information.

As far as I know:

1) Pay for the cost of Scepter's activation
2) Ability of Scepter resolves, Extirpate copy is placed on stack (or doesn't use the stack)
3) Extirpate resolves.

ARe there any complications in part 2)?

It helps to look up the Oracle text and relevant rules.


Isochron Scepter 2
Artifact
Imprint -- When Isochron Scepter enters the battlefield, you may exile an instant card with converted mana cost 2 or less from your hand.
2, T: You may copy the exiled card. If you do, you may cast the copy without paying its mana cost.

702.58a. Split second is a static ability that functions only while the spell with split second is on the stack. "Split second" means "As long as this spell is on the stack, players can't cast other spells or activate abilities that aren't mana abilities."

When you activate Isochron Scepter's ability, it goes on the stack. When that ability resolves, you may copy the imprinted spell and then cast that copy. When you cast the copy, it goes on the stack. If the copy has Split Second, spells cannot be cast and abilities cannot be activated until the copy resolves and is removed from the stack.

to provide an actual answer to your question: it will work just fine.

The opponent can respond to the activation of the scepter. When that one resolves, the extirpate goes on the stack. He can't respond to that one.

For all practical purposes, you lose the split second benefit against a clever opponent, but you don't lose the rest of the effect.
