If you would put one or more counters on a creature or planeswalker you control or on yourself, put that many plus one of each of those kinds of counters on that permanent or player instead.
Choose a Background (You can have a Background as a second commander.)
Lae'zel turns every counter you place into a counter-plus-one, snowballing +1/+1 counters, charge counters, and loyalty into overwhelming board states. You ramp counters out fast, pump a wide or tall board, and close with anthem-fueled aggression or +1/+1 counter payoffs. Pair her with a Background to fill in card advantage or recursion that mono-white otherwise lacks.
Add more counter replacement effects (Hardened Scales, Branching Evolution-style isn't in white, so lean on Conclave Mentor) and proliferate enablers like Evolution Sage analogs and Karn's Bastion to exploit doubling. Improve mono-white's weaknesses with strong card advantage (Welcoming Vampire, Esper Sentinel, Smothering Tithe) and fast mana (Sol Ring, mana rocks). Pick a Background like Raised by Giants or Cultist of the Absolute for extra threat density, and add protection such as Heroic Intervention's white cousin Flawless Maneuver to safeguard your counter investments.
