Arcades, the Patient

When Arcades, the Patient enters the battlefield,
each player creates 1 1/1 white Human token.
Whenever a creature attacks you,
draw a card and gain a Patience counter.
At the beginning of your End Step,
if you have 20 or more Patience counters,
you win the game.
Arcades, the Patient's Power equals the
number of Patience counters.
Remove a Patience counter: Draw a card.
"I will shield you from all harm."-Arcades
