Olivia, Opulent Outlaw

Two engines share a body here, and the seam between them is what the card is really about. The Treasure trigger reads "to a player," so it fires once per opponent your outlaws connect with rather than once per combat: a sweeping attack that lands on three players banks three Treasures, and that multiplayer multiplier is where the ceiling actually lives, not in any single hit. Those Treasures then fund the second half, which wants the opposite of a single big attacker. Three generic mana plus two sacrificed Treasures puts two +1/+1 counters on every creature you control, so the return scales with your board width: a lone body gains four points, a spread of six gains twenty-four. The cost is honest (you spend the very Treasures the first ability just generated, and the counters are not free), and the sorcery-speed clamp forbids using it as a mid-combat combat trick. The rhythm this creates is deliberately slower than a typical Treasure deck's burst: you accumulate across attacks, then convert the stockpile into permanent stats on a later main phase. The three-color identity does load-bearing work, since the creature types that count as outlaws span exactly red, white, and black; white supplies the go-wide anthem and lifelink stabilization, while the red-black half carries the sacrifice-and-Treasure texture. The card is built to reward a persistent, growing board over one explosive swing.
