Battle Mechanics
1. Zouchouten has Growth of All Things, granting Growth to 1 Shadow each turn. 2. If Jack Frost receives Growth, it becomes King Frost. If King Frost receives Growth, it becomes Black Frost and summons 1 Jack-o'-Lantern. Defeating the Jack-o'-Lantern reverts Black Frost back to Jack Frost.
Shares its sn-block (218xxx) with Kikuri-Hime and Arahabaki above. ⚠ Unlike Arahabaki (independently confirmed at Miyazawa's Palace by altema.jp), this thợ found no independent competitor source pinning Zouchouten's exact Palace — treat the sn-adjacency as a lead, not proof.
