, : Draw a card for each experience counter you have, then discard a card. Atreus deals 2 damage to each opponent.
Partner—Father & son (You can have two commanders if both have this ability.)
Atreus is a repeatable card-advantage and pinging engine: stack up experience counters, then tap him each turn to draw a fistful of cards, smooth your hand with a discard, and chip every opponent for 2. He wants a Father & son partner (or any experience-counter source) plus proliferate to scale the draw, while you grind toward a value- or burn-based finish in Izzet colors.
Refillable card advantage that scales with experience counters, outdrawing most tables in the late game
Built-in incremental reach damage that pressures all three opponents and enables a burn finish
Reach plus a 3-mana body makes him a fine early blocker against fliers and aggro
Partner flexibility lets you pick the best Father & son companion or run him with another partner-style strategy
The loot effect (draw then discard) fuels graveyard and discard-matters synergies
Does literally nothing without experience counters, so an empty board state leaves the ability blank
Heavily reliant on the commander staying alive and the activation cost each turn
Vulnerable to graveyard hate and removal that resets your experience-counter source
Izzet identity offers weak interaction with enchantments and limited efficient single-target removal
Discard requirement can hurt if you draw zero counters and must pitch a real card
Lets you keep the huge hands Atreus generates without discarding to cleanup.
Maximize experience-counter generation and proliferate density (Inexorable Tide, Evolution Sage, Karn's Bastion, Flux Channeler) so Atreus draws four-plus cards per turn. Add fast mana and cost reducers to activate him multiple times a turn, plus card-draw protection like Reliquary Tower and counterspell backup to keep him online. Cap it off with a tight spellslinger or storm finish to convert your card flood into a single decisive turn.
