Although they can be strong (especially the Bulbasaur line), all are weak to Fire, so a deck with a few good Fire Pokemon will have no problems
Despite either side of this token not being made frequently, the card still holds a high value
The downside here is that plotting an opponent's spell means they get to just cast it again on a later turn
The entire thing feels very juicy, from the spinning around of a bunch of the same packs to the swiping to rip off the top
I would try to get Umbreon into the game early on so you can start confusing your opponent's Pokemon, but if you can't get it out early, I would recommend putting it on your bench, attaching three energy cards to it, and waiting for your opponent to put a Pokemon with a lot of energy cards attached to it in the active Pokemon spot, I would then move Umbreon into that active Pokemon spot and use Shadow Shutdown until Umbreon is knocked out or retreated, I would hope to get lucky and flip 2 coins so my opponent would have to discard all their energy on that active Pokemon
