Shovel Knight: King of Cards is a successful union of its disparate halves, existing as both a platformer with consistently inventive level design and an engaging collectible card game. Joustus and the platforming offer a well-choreographed sequence of challenges that deliver constant variation. Half a decade later, this formula still holds up, and while it may have needed a booster shot of an entirely new sub-game, this injection is quite successful. It's a fitting send-off for a title that helped define a new wave of indies. By liberally borrowed the best aspects of games from the past while showcasing the strengths of modern design principles, Shovel Knight has earned its spot in the annals of the medium. Its latest installment lives up to that legacy.
