Forum:Tuner's scheme Q

My opponent synchro summon Arcanite magician and I have tuner's scheme set down. I know he gets priority so he get to be chain link 1 so he activate his effect to destroy my monster and i chain with tuner's scheme. What happen does my monster still gets destroy? Or vice versa lets say he target my set tuner's scheme and i chain with tuner's scheme. Do i get the monster and the effect disappear? I wanna know the correct resolve.
