Jaheira, Friend of the Forest

Tokens you control have "{T}: Add {G}."
Choose a Background (You can have a Background as a second commander.)

Brass's Bounty

For each land you control, create a Treasure token. (It's an artifact with "{T}, Sacrifice this token: Add one mana of any color.")

If you would create a Clue, Food, or Treasure token, instead create one of each.

For each token you control, create a token that's a copy of that permanent.

Commander creatures you own have "{1}, Sacrifice another creature or an artifact: This creature deals 1 damage to any target."
