Trample, haste
If you would put one or more counters on a permanent or player, put twice that many of each of those kinds of counters on that permanent or player instead.
If an opponent would put one or more counters on a permanent or player, they put half that many of each of those kinds of counters on that permanent or player instead, rounded down.
Vorinclex doubles all counters you place while halving (rounded down) what your opponents place, warping any counter-centric strategy in your favor. Ramp into Vorinclex by turn 5-6, then snowball +1/+1 counters, planeswalker loyalty, charge counters, and proliferate effects into overwhelming advantages. Win by going wide/tall with massive counter creatures or comboing off doubled counter engines while your opponents' planeswalkers and counter strategies collapse.
Add fast mana and ramp (Sol Ring, Mana Crypt, Carpet of Flowers, early dorks) to land Vorinclex on turn 3-4, and layer in stacking counter doublers (Hardened Scales, Branching Evolution, Doubling Season) for exponential output. Tighten the deck around a deterministic combo finish—Walking Ballista, Devoted Druid + Quillspike, or Sage of Hours—and pack mono-green protection like Heroic Intervention, Veil of Summer, and Snakeskin Veil. Trim slow value cards for proliferate enablers and a strong removal/ramp curve to close games before the table answers your engine.
