Responding to triggers

[Coffee Vampire]

If my opponent casts {Geist Honored Monk}, can I cast {Geth's Verdict} as a response to the monk's ETB trigger, so it will resolve before the spirit tokens come into play?

Yep!

The trigger from monk goes on the stack after its in the battlefield. So it would be a 1/1 (assuming no other creatures are out). Then you can respond to the triggered ability. {Gut Shot} {Geth's Virdict} {Shock} {Sorin's Thirst} etc.

So yessir I believe you can!
(unless Jester comes in here and ruins my moment!)

No moment ruining here.

Thanks all 3 of you.

But the tokens will still come into play. The triggered ability doesn't need the Monk on the BF to resolve.
