There's very few 1 prizers worth using and even cope options like chi-yu wont be able to kill yveltal in one hit. Unless it's a dedicated 1 prize deck like typlosion or apples you can essentially be walled. even after all that you need to have ex capability of ohkoing 350 HP too, possibly twice throughout a game. Without a simple means of gusting up the gengar this seems a little too degenerate
