At the beginning of combat on your turn, choose a kind of counter at random that Mechagodzilla, the Weapon doesn't have on it from among flying (This creature can't be blocked except by creatures with flying or reach.), first strike (This creature deals combat damage before creatures without first strike.), deathtouch, hexproof (This permanent can't be the target of spells or abilities your opponents control.), lifelink (Damage dealt by the creature also causes its controller to gain that much life.), menace (This creature can't be blocked except by two or more creatures.), reach (This creature can block creatures with flying.), trample (This creature can deal excess combat damage to the player or planeswalker it's attacking.), vigilance (Attacking doesn't cause this creature to tap.), and +1/+1. Put a counter of that kind on Mechagodzilla, the Weapon.
