1st edition pokemon cards value list Base (Base) Pokémon Card Set TCGplayer - Pokemon Base Set

I dont think this is really going to fly but combining this with Oblivion Ring, Leonin Relic-Warder, and related effects leads to a four card combo that will mill the opponent out on the spot using only cards that have decent utility all by themselves (other than the Altar, of course)

There is one link to Goldin Auctions, where it appears all bids are anonymous

With just two in each set, and with them being even rarer than Enchanted cards, these are likely to remain valuable for some time to come

As if that somehow wasnt enough, theres also the Cosmic Foil variant, which is even rarer than most serialized cards

While a lot more efficient than Sprout Swarm it is more easily disrupted and needs more tools to be able to get out of control as Swarm can on a bloated stagnant board
