Channel + Lich's Mirror + Emrakul

[TorpidNinja]

Now I have a Lich's Mirror question:

I cast Channel while at 20 life. I spend 5 life to play Lich's Mirror, which resolves. Can I now announce Emrakul, pay the 15 life to get it on the stack, remain alive from the Mirror trigger, and still end up with Emrakul in play?

I'm pretty sure this works, but I may have some timing off.

You can do this while being on twenty or more life.
But please do not forget that you can not pay more life then you have.
If you are at 14 life you can not pay for Emrakul.

This works because while the Mirror triggers Emrakul is already/still on the stack.

Losing the game from 0 or less life is a SBA, and SBAs are only checked just before priority happens. If you activate Channel while in the "activate mana abilities" step of casting Emrakul, Lich's Mirror won't have anything to replace until after Emrakul is on the stack.
