Queen Allenal of Ruadach's power and toughness are each equal to the number of creatures you control.
If one or more creature tokens would be created under your control, those tokens plus a 1/1 white Soldier creature token are created instead.
Flood the board with creature tokens, getting a bonus 1/1 Soldier every time you make any token, then convert that wide army into damage via anthems, overrun effects, or a big swing with Queen Allenal herself (who grows with your creature count). You build a critical mass on turns 3-5 and close games by going wide and pumping.
Free extra Soldier on every token-making spell or ability stacks up incredibly fast
Cheap, resilient commander whose stats scale automatically with your board
GW has the best anthems, overrun effects, and token enablers in the format
Wide boards play well with convoke, ramp, and counter synergies
Extremely vulnerable to board wipes given the all-in go-wide plan
No built-in evasion or trample—gets gummed up by ground blockers
Allenal does nothing on her own without other creatures to power her
Lacks card advantage and interaction inherent to the colors; can run out of gas
