Leaping Ambush

Most one-mana green tricks pick a lane: they push a race with a lopsided +3/+1 or hold a line with a bump to toughness. This one refuses to choose, and the untap clause is why. A creature you already attacked with can throw itself back into blocking position on the crackback; a tapped-down blocker can suddenly stand up and eat something the opponent had counted as safe. The reach grant is the third lever, and it earns its slot: instant-speed reach lets a grounded body reach up and answer a flier mid-combat, a blowout pump spells rarely get to offer because the trick and the evasion problem usually cancel out. The stat split points to intent. A +1/+3 wants to survive the exchange and keep the creature on the board, not trade up and race, so the card leans defensive even while the untap opens offensive lines. Bundling a survivable buff, a combat reset, and instant-speed reach onto a single green mana produces a trick that operates on both sides of the same combat step, a wider window than the rate would suggest.
