Legendary gambler's lucky deck.
Final Trump is the strongest weapon for Setzer, found only in the Advance and later versions by defeating Ice Dragon at the Dragons' Den, or by betting the Scorpion Tail and winning at Dragon's Neck Coliseum. It provides 215 Attack, 230 Hit Rate, +4 Speed, +4 Strength, +3 Stamina, is long range, and consumes MP when attacking to deal an automatic critical hit.
A trump is a playing card which is elevated above its normal rank in trick-taking games. Typically an entire suit is nominated as a trump suit—these cards then outrank all cards of plain (non-trump) suits. In other contexts, the term trump card can refer to any sort of action, authority, or policy which automatically prevails over all others.
