Whenever Omo enters or attacks, put an everything counter on each of up to one target land and up to one target creature.
Each land with an everything counter on it is every land type in addition to its other types.
Each nonland creature with an everything counter on it is every creature type.
Omo turns one land into a do-anything five-color source and one creature into a member of every tribe each time she enters or attacks, fueling both perfect mana and typal payoffs. Early game you ramp and fix with everything-counter lands while developing a typal board; mid-game you stack lords and anthems on creatures that now count as every type. You close with a wide, pumped tribal board or a single oversized threat carrying every keyword's worth of buffs.
Add proliferate enablers (Flux Channeler, Evolution Sage, Tezzeret's Gambit) to multiply everything counters and accelerate your payoffs. Lean into a clear finisher—Craterhoof Behemoth, Finale of Devastation, or Pathbreaker Ibex—plus tutors (Worldly Tutor, Chord of Calling) to find Maskwood Nexus reliably. Tighten the mana with fast rocks and protection (Heroic Intervention, Lightning Greaves) so a wipe doesn't reset your concentrated board.
