Pouncing Cheetah

Flash is the entire payload here, and the design leans into that starkness. Green has no shortage of efficient 3/2 bodies for three mana; what this one buys is the right to deploy it at end of turn, after combat, in response to a sweeper announcement, or as a surprise blocker that turns a profitable attack into a bad trade. The body is otherwise plain by construction: a French-vanilla creature whose only text is the keyword, a design that exists to demonstrate what flash does to combat math without a second ability muddying the lesson. Green rarely gets ambush bodies of this caliber, so the value sits almost entirely in timing rather than rate. You hold up the mana, keep the threat off the table where it can ambush an attacker or punish a tapped-out opponent, and convert deck-builder predictability into in-game information advantage. Strip the flash and this is a creature nobody writes about; the keyword is what makes the same stats worth holding instead of slamming.
