Jolene turns big-butt aggression into a snowballing Treasure economy: swing with fat creatures to generate Treasure, then either ramp into more threats or convert Treasures into burn via her own ability. You play a Gruul midrange beatdown deck that wants to deploy 4-power creatures fast, attack every turn, and use the Treasure flood to pump out damage or fix into game-ending spells.
Generates ramp and fixing simply by attacking, accelerating you ahead of the table
Built-in repeatable reach/removal pinging through Treasure sacrifice
Big creatures pair naturally with Gruul's best beaters and trample enablers
Treasures fuel artifact synergies, sacrifice payoffs, and explosive double-spell turns
Low to-the-table impact if creatures get removed before attacking
Wide token strategies can stall her since she rewards individual high-power attackers
No card advantage engine on the command zone—can run out of gas
Vulnerable to board wipes that erase your attackers and Treasure-makers
Generates an army of attackers and feeds artifact/aristocrat payoffs around Jolene's Treasures.
Add more Treasure-payoff redundancy (Mayhem Devil, Reckless Fireweaver, Disciple of the Vault-style pingers) and Treasure doublers like Goldspan Dragon to turn each trigger into damage. Lean into reliable 4+ power enablers (Xenagos, Embercleave, anthem effects) and a Craterhoof/Finale of Devastation finisher so the deck can pivot from grind to one-shot kills. Tighten the mana with fast ramp (Sol Ring, Smothering Tithe, Birgi) so Jolene's Treasures snowball into explosive, game-ending turns.
