Adeline, Resplendent Cathar is great mono white commander for white weenie and creature token decks. Adelines trigger can give multiple ETB triggers and the newly created tokens are easily sacced for extra value like card draw or milling to opponents.
White has many great support spells and permanents for +1/+1 counters theme. Counters theme is often combined with White-weenie or token strategy and turns the small creatures into a formidable force.
Mono white token decks aim to create a mass of small creature tokens and then with anthem effects or +1/+1 counter defeat the opponents in combat. White token decks are aggressive decks and aim to flood the battlefield soon rather than later due to the weaker card draw mono white has access to.
