A level-sixty-five ghost deckmaster uses a bloated Precision deck and four Swordfish bodyguards before Raul cuts down its dive suit.
The Reef Explorer waits at the foot of the key mound in an ethereal deep-diving suit similar to Zev's dungeon gear. As a ghost-class enemy, it requires magical damage.
Four level-fifty Swordfish Interlopers guard the deckmaster. The Explorer summons two more swordfish totems, then repeatedly stacks Precision on one of them while its bodyguards attack Carl and Mongo.
Lazarus's plague removes the remaining fish. The Explorer flees into dark trees and tries to play more cards, but its utility-heavy deck cannot produce another usable totem. Donut speeds Raul, whose glowing claw severs the suit's leg and releases ghostly water, killing it.
Its drop contains roughly forty to fifty cards, including thirty Precision utilities, four total totems, and no traps.

The Explorer is token six's deckmaster and a warning that a bad deck can still create one near-guaranteed lethal attack.
