, Remove a counter from a nonland permanent you control: Draw a card.
O'aka turns counters into cards: each turn you tap her, pull a counter off any nonland permanent you control, and draw. Build an engine that constantly restocks counters (proliferate, +1/+1 sources, charge counters, planeswalkers) so you always have fuel, then snowball card advantage in mono-blue and win with the resources you've stockpiled. You play a controlling, value-grindy game and bury opponents under card flow.
Add untap effects (Seedborn Muse, Pemmin's Aura, Freed from the Real) so O'aka draws multiple cards per turn cycle, and lean harder into proliferate (Inexorable Tide, Flux Channeler, Evolution Sage if splashing) to never run dry. Tighten the mana with charge-counter rocks (Astral Cornucopia, Everflowing Chalice) that double as fuel, and include a clean win like Laboratory Maniac or a big X-draw spell so the card advantage actually closes games.
