# Marill #15/30 — HS trainer Kit (Gyarados)

## Summary

Marill is a Johto-born Water type with a durable fan following, a round, cheerful design that keeps it a favorite among collectors of the Gen II starters' era. This is a trainer kit card, so it was a deck-building piece for newcomers rather than a pack chase, and Kouki Saitou's illustration is the draw. At a $1.59 modelled guide, up 3% over 30 days on 2 copies traded, with 212 days of inventory on the board, this printing is almost entirely collector premium, since the same card plays for $0.15 out of Ascended Heroes; no PSA population is on file.
