Grompus, Devoted Dervish

Soulbond (You may pair this creature with another unpaired creature as either enters the battlefield. They remain paired as long as you control both of them.)
As long as Grompus, Devoted Dervish is paired with another creature, both creatures have +2/+2, lifelink, and intimidate.
Non-hybrid mana symbols in the mana costs of permanents you control count for an additional devotion of that color.
