Slickshot Vault-Buster

The base body is defensive to a fault: a 1/4 with vigilance holds a corner all day and threatens nothing, which is by design. The crime condition inverts it. Once you've pointed anything at an opponent (a spell, a removal effect, even a graveyard exile) the same turn, the toughness stays put while the power jumps to a 3/4 that has already attacked and can still block. Vigilance is the load-bearing keyword here: the buff is contingent on doing something aggressive, and vigilance means the reward for doing it doesn't cost you your defensive shell. What makes the design tidy is how low the bar sits. Crime is one of the widest triggers in the mechanic's vocabulary; most decks that want a blue three-drop are already targeting the opponent with counterspells, bounce, or interaction as a matter of course, so the +2/+0 is closer to a default state than a hoop to clear. The result is a body that reads as a value blocker but plays as a fine attacker in any deck built to interact, which is most of them. It rewards the play pattern blue is already going to run rather than asking you to bend around it.
