A level-50 giant mouse from Indian mythology whose challenge-mode spell never completes before Shi Maria eats it.
Mushika appears as the arena's challenge-difficulty opponent after hours of lower-level practice. The giant mythological mouse or rat is only level fifty despite the supposedly elevated mode.
It begins summoning or casting an unknown effect, but Shi Maria reaches it first. She paralyzes the deckmaster, opens her jaw, and consumes the creature whole.
Because the unfinished ability never resolves, Carl cannot judge why Mushika qualified as a challenge opponent. The quick deckmaster strike still satisfies the win condition and unlocks the next mode.
A giant mythological mouse surrounded by an unfinished summoning circle as a spider descends.
Mushika is the unexpectedly easy challenge opponent whose defeat unlocks Secret Challenge Mode.
