Changeling, Reach,

Other multicolored creatures you control get a +1/+1 for every color after the first in their color identity

At the beginning of combat on your turn, create 2 Shapesplitter tokens. One that's a 3/1 with Reach and one that's a 1/3 with "Sacrifice this token: Draw a card" As long as there is a Shapesplitter token on the battlefield, Neeko has Shroud

"Stand back! Big strong Neeko coming though!"
