I just had a idea for a card that is a permanent version of anyone famous monocolored spell, like a living fog. That card could also care about monocolored, so to take the living fog as an example: A green creature for like four green mana with 1/4 which has: "As long as you control three or more forests, creatures your opponents control, deal no damage to you in combat phase."
