Undercover Crocodelf

The whole gag lives in the type line: an Elf Crocodile Detective, three creature types stacked into a pun the mechanics then quietly justify. Disguise is the vehicle for the reveal. Cast it hidden as a face-down 2/2 with ward, then flip it up when the moment demands and drop a 5/5 into a board that read it as filler. That face-down window is the design's real trick: disguise turns a six-mana beater into a threat you can deploy early, hold back, and unmask at instant speed to break a combat math the opponent thought they had solved. Investigate is the payoff for connecting; every unblocked hit banks a Clue, converting combat damage into deferred card advantage a green-blue midrange body is happy to sit on. The two keywords pull in the same direction. Ward guards the hidden card from cheap removal while it waits, and the flip ambushes the block to break through toward the Clue engine. A 5/5 for six is an unremarkable rate on its own; the interest is in how much of the card's value is optional and timing-dependent, held behind a mask and unlocked on your terms. This is a set-mechanic showcase built to be legible: Detective for the flavor, Investigate for the Clue subtheme, Disguise for the mystery. It carries its costume well.
