Just a thought which I probably know the answer but it's mulling in my brain. In this example let's say I have all the needed mana. I have a {Chatter of the Squirrel} in the grave yard and a {Elixir of Immortality} on the battle field. If I cast my Chatter and then use Elixir stacked such that Elixir resolves first what happens to Chatter?
The Chatter isn't in the graveyard, so it doesn't get shuffled it. It's currently on the stack waiting to resolve.
Yup that's what I thought just for some reason it was bugging me. Thanks for curing the crazy!
