Ma'ateriel's Gift

(Ma'ateriel's Gift is blue)
Each player draws X cards. X can't be greater than your devotion to blue (Each {u} in the mana costs of permanents you control counts toward your devotion to white.)
As Uriell's rebellion and Leliyel's betrayal brought war to Taav, Ma'atariel secluded himself away from his siblings' quarrel, quietly directing his disciples through enigmatic messages in the waves.
