Athena, Selfless Savior

Defender, ward {2}. X is equal to the number of cosmos counters on Athena. Saint creatures you control get +1/+1 and have vigilance. Whenever an ability of Athena resolves, remove two cosmos counters from her. {W}: Target creature gains protection from the color of your choice until end of turn. You gain half X life, rounded up. {1}{U}: Counter target spell unless its controller haves you draw half X cards, rounded up. {2}{B}: Return target creature with mana value X or less from your graveyard to the battlefield with a finality counter on it. {3}{R}: Athena deals X damage to each opponent. {4}{G}: Exile the top 5 cards of your library. Put up to X permanents from among them onto the battlefield and shuffle the rest into your library. When the last cosmos counter is removed from Athena, transform it.
