Anax's power is equal to your devotion to red. (Each in the mana costs of permanents you control counts toward your devotion to red.)
Whenever Anax or another nontoken creature you control dies, create a 1/1 red Satyr creature token with "This token can't block." If the creature had power 4 or greater, create two of those tokens instead.
Anax is a resilient mono-red aristocrats/aggro commander that turns your dying creatures into a stream of Satyr tokens, then converts those bodies into damage. Flood the board, sacrifice and attack repeatedly, and use the token engine to grind through removal and board wipes while pushing devotion-fueled aggression.
Indestructible by default (returns as an enchantment, only dies via state-based devotion check)
Generates value off board wipes and removal, blanking them
Cheap 3-mana commander that's hard to permanently kill
Synergizes with sacrifice outlets, big-power creatures (two tokens), and go-wide payoffs
Mono-red lacks reliable card draw and recursion compared to other colors
Satyr tokens can't block, leaving you defensively weak
Token swarm is vulnerable to wraths that exile and to fogs/edicts
Devotion can collapse if your board is removed, sending Anax to the graveyard
Each token entering deals damage and he adds heavily to red devotion, pumping Anax.
Add fast mana and devotion-boosters like Nykthos, Shrine to Nyx and double-pip permanents to keep Anax huge, then tighten the aristocrats core with Pitiless Plunderer, Mayhem Devil, and free sac outlets. Lean into damage doublers (Fiery Emancipation, Torbran) and card advantage engines (Skullclamp, Outpost Siege) to offset mono-red's draw weakness and close games faster.
