wotc
Xenagos's first ability isn't a mana ability. It uses the stack and can be responded to. Count the number of creatures you control as the ability resolves to determine how much mana to add. You choose how much of that mana is red and how much is green at that time.
wotc
Creature cards with bestow put onto the battlefield with the third ability will be creatures on the battlefield, not Auras.
