For one thing, the cards status as a promotional card has to be a factor
most other cards are just really good sticks that are difficult to out
That's very strong, and you can easily build around it as a way to make a free dork without jumping through any mana or cards or tapping or "once per turn" or anything else
Even in the 90s, I had a sizable collection of Digimon cards and miniatures but I never found the time to learn how to play the card game
Hope you can find it in the top four cards
