the umbreon he was playing was doing 60+ a turn to gengar....
and compound pain is way to slow
I'd be more worried about people trying to be clever and sticking 1-1 Umbreon into something like Sableye...
Shouldn't you have 2 energy attached to Gengar anyway? Drop a Bat or something and Shadow Room in the same turn... iunno. Leveled Up, they take 3 turns to kill you anyway.
Besides, they have to bite Fainting Spell anyway, given the history of this deck that shouldn't be such a bad thing.
If you are really concerned then Relicanth would be the play, but I wish you luck getting out that tech energy...
Running Cyrus doesn't help you that much. It doesn't show up all that often, and under trainer lock, how are you going to get the Relicanth? Barring lucky draws, it's gonna be playing one supporter, then supposedly Cyrus right after (or other way around but that's actually slower).
In the time it takes you to get out Relicanth they will have slain a Gengar already.
Honestly, not many people are playing umbereon. There are none in my meta, and I doubt yours is full of them
Whether or not you ran Luxury Ball wasn't the point, it's a matter of, how are you going to get Relicanth and the Energy reliably and quickly enough, PARTICULARLY with no trainers whatsoever, to counter Umbreon before Umbreon does enough damage to cost you the game?
