Alter of Warrior

Each of your upkeeps, you may have your
opponent take control of all creatures you
control and you take control of all creatures
your opponent controls until end of turn.
{w}{b}: Untap all creatures you control. They
gain haste until end of turn.
"They come to me and they say 'Defend me,
o' powerful; guard me; take control of my soul; fight
for me.' But these fools think nothing of who I really
am."
