So this is an early version of Pokemon card alternate art!) Unlike Magic: The Gathering, though, most promo cards were totally original designs
To raise a Digimon partner, the player must train it, feed it, let it rest, and take it to bathrooms
Cait, Cage Brawler offers discard, but not much else
The first card that previewed stun counters was Impede Momentum, which puts three stun counters on a creature
I believe that, while Quick-Play is cool, it should be a Continuous Spell since it remains on the field until the 3rd Kuriboh, and since it's a Quick-Play it cannot "get destroyed" for the final "draw 1 card effect"
You can also add these cards to your existing Dinosaur, Sea Serpent, or Wyrm Decks to boost their champion caliber
