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.

All Sliver creatures have poisonous 1. (Whenever a Sliver deals combat damage to a player, that player gets a poison counter. A player with ten or more poison counters loses the game.)

Sliver creatures you control have "{T}: Add one mana of any color."

All Sliver creatures have haste.

{T}: Add {C}. {T}: Add one mana of any color. Spend this mana only to cast a Sliver spell. {5}, {T}: Create a 1/1 colorless Sliver creature token. Activate only if you control a Sliver.

Choose a creature type. If you control more creatures of that type than each other player, you gain control of all creatures of that type. (This effect lasts indefinitely.)

Whenever a Sliver deals combat damage to a player, its controller may draw a card.

Sliver creatures you control have "When this creature enters, goad target creature an opponent controls." (Until your next turn, that creature attacks each combat if able and attacks a player other than you if able.)

Replicate {1}{G} (When you cast this spell, copy it for each time you paid its replicate cost.) Each Sliver spell you cast has replicate. The replicate cost is equal to its mana cost. (A copy of a permanent spell becomes a token.)

All Sliver creatures have flying.

All Sliver creatures get +1/+1.
