Black mana adds some removal and life drain effect to the deck, and Gilt-Leaf Winnower is a semi-evasive 4/3 that can kill a non-Elf when it enters the battlefield if it doesn't have "square stats" (same power and toughness)
You pay for a scalable wheel based on your devotion, then another six to flip into the saga, Ifrit, Warden of Inferno and basically destroy a creature as a 9/9 before ramping up to do it again
A 1/1 Angel with flying and first strike for one white mana is okay, but giving all of your creatures both abilities for one mana is amazing, and only gets better as you play more creatures
Opponents have to pay life equal to Raubahns power just to target it, and with the right equipment, that cost can get painful fast
Time to search the couch for 845,000 pennies.
