Ruling Gengar SF and Fainting Spell

[Cinema]

If I KO a SF Gengar through damage, for example with Gyarados's Tail Revenge, do they send up the next Pokemon before or after they flip for Fainting Spell? Basically what I'm asking is if you can use Gengar Prime's Catastrophe Poke-Body to Lost Zone a Pokemon that has been KO'ed by Fainting Spell.

They flip for Feinting Spell before replacing the pokemon. So, technically, no. You cannot Catastrophe a pokemon knocked out by Feinting Spell.

To add to that, if a Pokemon has a Poke-Body, after resolving things after the attack, such as prize checking, the Poke-Body of that Pokemon is nullified and has no effect. Example is RDL's Space Virus (if it knocks out a Dialga GX, you take 2 prizes, because Time Crystal is not in effect anymore).
