Budget Political Kraj (EDH / Commander)

Experiment Kraj can steal the activated abilities of anyone with a +1/+1 counter. Abuse this.

Kraj can get infinite mana: Eperiment Kraj + Gyre Engineer + Horseshoe Crab/Simic Ragworm/Freed From the Real. And can color filter that mana to blue with Orochi Leafcaller. (As you need to specify an amount; let's say 100) 100 blue mana means 100 times you can tap and untap Kraj for +100/+100 on Kraj + Kaseto, Orochi Archmage/Herald of Secret Streams with commander damage.

Or, could double the counters of your other creatures with Kraj + Gilder Bairn for a wider sweep / attack all opponents ftw. Especially if cannot find leafcaller to filter for blue.

Or, self mill with Laboratory Maniac + Kraj + Fathom Mage/Benthic Biomancer (Draw 100 cards to win the game).

Or, assuming the 100 blue mana + Simic Manipulator, could take all opponents' creatures as your own.

The deck also plays very politically. Give mana to other players, give +1/+1 counters to other players, prevent combat damage, give opponents' creatures shroud... see politics 101.

Will take notes - was up all night when I made this list, so maybe I missed something, overlooked something, etc.
