Myrkul, Lord of Bones says "whenever another non-token creature you control dies, you may exile it. If you do, create a token that's a copy of that card, except it's an enchantment and loses all other card types.
With Athreos, Shroud-Veiled, I can put coin counters on creatures and "whenever a creature with a coin counter on it dies or is put into exile, return that card to the battlefield under your control."
Similarly with Kaya the Inexorable, ghostform counters give non-token creatures "When this creature dies or is put into exile, return it to it's owner's hand and create a 1/1 white Spirit creature token with flying."
If I control all three of these cards and one of my other, non-token, legendary creatures with a coin counter and ghostform counter dies, what happens?...
I'm assuming I have to choose between the two counter's triggers and can't get a spirit and the creature on the battlefield, but can I choose one of those triggers and get the enchantment?
If my opponent had something like Grave Betrayal which says "Whenever a creature you don't control dies, return it to the battlefield under your control with an additional +1/+1 counter on it at the beginning of the next end step." would I be able to exile it, get the enchantment, then they get the creature?
Sorry there's a lot of confusing questions, thanks for the help in advance.
