You can cast it from exile no matter what # you get, and then you can either spend mana to cast it with mana of any color usable and then you can get it for free with the higher roll
You could build one around food (Hot Soup!) holidays (Zedruu the Greathearted = Santa Claus), family members, your favourite metal band, actual MTG artists, even an all vanilla creatures deck for the blandest of the bland
No one, as far as I know, has ever gotten past one
Mountains Matter Another advantage of playing mono-red is access to cards that care about Mountains, with a prime candidate being Valakut, the Molten Pinnacle
This isnt just an issue when it comes to constructed
For one extra mana, you get +1 power and a creature that wont rush headlong into a terrible attack
