Most of Arcana Force have kinda creepy artwork. Funnily enough, the original tarot cards didn't have anything creepy in them... well maybe aleister crowley contributed to give them a bad rep but that artwork is not really popular I'd say.
You won't often Summon this thing (though the fact it's a 2400 beatstick can come up). It's the fact it's copies 7-9 of Kuriboh (3 Kuriboh, 3 Temperance, 3 Flute/Sphere Kuriboh, so I guess maybe 12 depending on how you count it) they're likely worried about, given how obnoxious stall decks already are.
