Eminence — At the beginning of combat on your turn, if Arahbo is in the command zone or on the battlefield, another target Cat you control gets +3/+3 until end of turn.
Whenever another Cat you control attacks, you may pay . If you do, it gains trample and gets +X/+X until end of turn, where X is its power.
Arahbo is a Selesnya Cat tribal/Voltron deck that buffs a single attacker into a one-shot threat via Eminence and the doubling combat trigger. Build a wide Cat board, suit up one creature with equipment/auras, and use Arahbo's pumps plus double strike to deal lethal commander damage. You operate from the command zone, so the strategy works even if Arahbo never hits the battlefield.
Eminence works from the command zone, giving free +3/+3 every combat regardless of removal
Power-doubling combat trigger creates explosive one-shot kills, especially with double strike
Strong, deep Cat tribal package with good lords and anthems
Green-white access to ramp, protection, and consistent threats
Heavily reliant on a single attacker—targeted removal or blockers can blow you out
Vulnerable to board wipes that erase the wide Cat support
No card advantage engine baked into the commander
Telegraphed combat damage strategy that savvy opponents play around with fogs and instant-speed removal
Scales with your Cat count and makes more Cats, snowballing your board presence.
Add fast mana and ramp (Sol Ring, Three Visits, Nature's Lore) to deploy Arahbo's payoffs earlier, and lean into double strike enablers (Fireshrieker, Grappling Hook) for guaranteed one-shots. Include protection like Heroic Intervention and Lightning Greaves to insure your single attacker, and prioritize evasion plus haste to reduce the deck's reliance on slow combat steps. Trim weaker vanilla Cats for value creatures and an Eladamri's Call/Worldly Tutor package to find your key buff target.
