Whenever Kari Zev attacks, create Ragavan, a legendary 2/1 red Monkey creature token. Ragavan enters tapped and attacking. Exile that token at end of combat.
Kari Zev is a mono-red aggro/Voltron commander that comes down turn two and starts attacking immediately, bringing Ragavan along for an extra 2 power each combat. You suit her up with cheap equipment and combat tricks, push damage through her menace and first strike, and grind opponents down before reloading with red's relentless card advantage. The deck plays a fast, proactive game and closes through repeated commander damage or a wide red beatdown.
Extremely cheap, hard-to-block 3/1 first strike body that effectively attacks for 5 with the Ragavan token
Two-mana commander means easy recasts and minimal commander-tax pressure
First strike makes her safe to swing into most blockers and a great equipment carrier
Ragavan tokens fuel attack-trigger and aristocrat/sacrifice synergies each turn
Mono-red lacks card draw, ramp, and removal depth compared to other colors
Low base toughness makes Kari Zev vulnerable to ping effects and cheap removal
Voltron strategy is fragile to single-target removal and getting blown out for tempo
Struggles against go-wide token decks and big lifegain/fog strategies
