first edition grimer pokemon card - Dragon flip a coin Pokémon First Edition Trading Card

The flip side of the card offers the rewards associated with completing the minigame

My inclination towards this is based on personal witness of similar things at PBM

For every creature type the set cared about, we wanted to check that we weren't printing a card that had that particular type "hidden." We didn't want players to have to look up creature types for every new creature card that was passed to them during a draft

This sort of card rarely breaks into Constructed formats, as theres simply more threatening or aggressive things to do for four mana in the kinds of decks that would want it

Once you disturb it, itll provide an alternate win condition, making one opponent lose the game once it hits three counters on your upkeep
