Whenever you attack, you may pay and sacrifice an Aura attached to Three Dog. When you sacrifice an Aura this way, for each other attacking creature you control, create a token that's a copy of that Aura attached to that creature.
Suit up Three Dog with cheap, powerful Auras, then go wide so that on attack you pay , sacrifice an Aura, and copy it onto every other attacker. A single buff or evasion Aura instantly becomes a board-wide enchantment, turning a token swarm into a lethal alpha strike. You play a hybrid Auras-matter and tokens deck that wants both creatures and enchantments on the battlefield at once.
Turns one Aura into many copies, generating absurd value and explosive damage from a single card
RW gives access to the best go-wide token producers and aggressive curve
Copied Aura tokens dodge being two-for-one'd by removal since the original is sacrificed anyway
Low mana value (3) commander that's easy to recast and protect with cheap Auras
Requires assembling both a board of creatures AND an Aura on the commander, making it vulnerable to disruption
Board wipes and creature removal reset everything, and you over-commit to the board
Aura-based strategies suffer hard from spot removal on Three Dog (card disadvantage)
RW lacks card draw and ramp, so flooding out or running dry is common
No native evasion or protection on the commander itself
Flexible white removal that keeps your aggressive plan clear of blockers and threats.
Prioritize cheap Auras with high impact and enchantress-style draw (Sram, Sage's Reverie, Setessan Champion) so you never run out of gas. Add token enablers and anthem effects to widen the board before the copy trigger, and include resilience like Sigarda's Aid, Hardened Scales-style scaling, and protective Auras to survive removal. Cut clunky single-target Auras for ones that pump or grant evasion, and add fast mana (Sol Ring, signets) plus a couple board-wipe insurance pieces.
