Emperor's Vanguard
Explore was built to launder card advantage through combat, and this is the cleanest test case the mechanic produced. The reward is conditional on connection: hit a player, dig a card deep, and either bank a land or grow into a harder body to block. The 4/3 frame is the load-bearing decision here. Toughness three keeps it honestly killable, but power four means it trades up profitably and survives the first explore that lands a +1/+1 counter, after which it shrugs off most early-game removal that cared about three. The mechanic resolves a long-standing tension in green's beatdown creatures: a 4/3 that just attacks runs out of gas the moment the board stalls, while this one converts every unblocked swing into selection, smoothing draws and snowballing its own size. The give-back clause (return the nonland to the top or bin it) is the quiet skill check, letting you set up the next draw or feed a graveyard rather than locking the card into your hand. None of it triggers without combat damage, so the whole package is a wager that you can keep it swinging, which suits green midrange's whole reason for showing up: relentless, unblocked pressure. A creature that pays you to do the thing you already meant to do.
