Maximum Overdrive
A combat trick that answers the two questions blockers ask at once: can I trade up, and can I survive the trade. Deathtouch means the buffed creature kills anything it touches; indestructible means nothing the opponent throws back sticks, whether that's chump-block chip damage, a burn spell, or the deathtouch on their own attacker. The +1/+1 counter is the piece that outlasts the turn: while the keywords evaporate at end step, the stat bump is permanent, so a two-mana instant leaves behind a bigger creature after having already won the exchange it was cast in. That combination turns a favorable block into a blowout and an even race into a lopsided one, since the defending player has no math that beats a creature that both kills on contact and cannot die. The instant-speed timing is doing the real work: held up on the opponent's turn, it converts an attack step into a trap, letting a small body eat a much larger attacker and walk away larger than it started. Black rarely gets to fight this cleanly (its removal usually costs the creature its own life or a sacrifice), so a pure pump-and-protect package in the color reads as a small departure from how black usually handles combat.
