1/2

I'm trying to figure out, if I top deck Turn//Burn, with Kefnet out, I reveal and get a copy to cast. Now if I want to cast both parts using the fuse ability, what happens?

  • Do both sides get discounted, so I'm paying it for effectively one blue and one red? -Does only Turn get discounted because it occurs first? -Do I get to choose which side is discounted?
