That reaction is exactly what you're giving someone
The rules were as follows: There are no deck, discard pile, or prize cards Players start the game with all 6 cards from their pack in their hand The first player to knock out all of the opponents Pokemon wins
The only thing more horrifying than the artwork of Bite Shoes is that it only depicts one shoe
The reason I'd put two of these in a deck, is because you could use one right away in the active Pokemon spot, then if you include this card in a spread damage type deck, you could put the other Volbeat card in the active Pokemon spot later in the game and use Luring Glow, move one of your opponent's weak Pokemon into the active Pokemon spot and then knock it out with either Volbeat or another Pokemon your next turn
But thats not an option in Standard, and I wouldnt be surprised if literally every white deck next month has at least two copies of Deicide in the sideboard
If you like the idea but find this to be a bit intimidating, then you can try some of the smaller scale ideas I mentioned at the start
