The Masked One

When The Masked One enters the battlefield,
tap up to two creatures. If The Masked One is
still alive after two upkeeps, untap the
tapped creatures, they gain First-Strike
and Double-Strike until end of turn,
exile The Masked One.
If The Masked One dies before your
second upkeep, exile tapped
creatures tapped by The Masked One,
then sacrifice The Masked One.
