Whenever a player attacks one or more of your opponents, that attacking player creates a Treasure token.
If you would create one or more Treasure tokens, instead create those tokens plus an additional Treasure token.
Sacrifice five Treasures: Put five +1/+1 counters on Jolene.
Flood the board with Treasure tokens by encouraging combat (everyone makes Treasures when attacking, and your own production is doubled), then convert that ramp into oversized threats, big X-spells, or sacrifice payoffs. You build a mana advantage every turn while Jolene herself can balloon into a one-shot kill via her counter ability. Win through commander damage, explosive ramp into haymakers, or Treasure-fueled aristocrats/storm finishes.
Doubles all your Treasure creation for absurd ramp and fixing
Turns every attack from any player into resources, including political incentives
Jolene's counter ability makes her a fast voltron clock with trample support
Excellent in artifact-sacrifice and 'sacrifice an artifact' synergy shells
