I was fortunate enough to get one in a Booster Box, but you can find it for fairly cheap on TCGPlayer, with a card that is a must-have addition to your library
Cut a Deal is a card I admittedly passed over initially, but I think it fills a particular role that each deck wants at least some of: consistent draw that requires the least board investment to accomplish
It's a funny trick, but no one should be surprised Konami finally got tired and banned it

Use Munkidoris Adrena-Brain Ability (Once during your turn, if this Pokmon has any [D] Energy attached, you may move up to 3 damage counters from 1 of your Pokmon to 1 of your opponent's Pokmon.) to move generated damage counters off your Pokmon onto your opponents Pokmon, gradually spreading damage on their board

Then, place the rest at the bottom of your deck in any order and trash 1 card from your hand
