2. With the gating trigger on the stack, you play the second Stalker. If they target(2) Harpy in response to you casting Stalker 2, or the gating trigger, pay a life to return Harpy. If they target either Stalker, just bounce the other one. Allow the trigger of Stalker 2 to resolve. If they target it with the trigger on the stack, re-cast Harpy. If they then have the third(3) removal for Stalker in response to you casting Harpy again you're done unless you have a 3rd effect somewhere. You then just use the Stalker 2 trigger after it dies to Recruiter it up. Usually E. Witness. Otherwise, you return Stalker, re-cast Harpy, and again with the gating trigger on the stack, re-cast Stalker. This time, get Recruiter for Strix. Pay a life. Rinse. Repeat.
So they have to be able to play 3 instant speed removal effects on 3 separate targets in one phase. And sweepers at best still count as one. And even that's no good if you have a Witness available unless all 3 are Plow.
