Retain Priority?

[HarlequinCasts]

Is it possible to retain priority when responding to something?

Example:

Opponent casts a spell.
I want to counter it but need to crack a fetch for the right mana.
After I crack the fetch the stack resolves without an opportunity to counter the spell.

Sorry if this is a basic key press or something. Thanks!

The problem here is that Counterspell can't target anything but the top card on the stack. (That doesn't strike me as being right even under the fourth (fifth?) edition rules Manalink runs under.) So once you respond with your fetchland, you can't target the prior spell anymore.

This is possible for us to fix now with a fair bit of effort - we've got working C implementations of Counterspell and the targeting functions, and know how to inspect and counter arbitrary cards (and effect cards) on the stack. It's still not trivial by any means, though.

Thank you. Good to know!
