Sloth

Suspend 5 - {u}{g} (Rather than cast this card from
your hand, you may pay {u}{g} and exile it with 5
time counters on it. At the beginning of your upkeep,
remove a time counter. When the last is removed, cast
it without paying its mana cost. It has haste.)
Provoke (Whenever this creature attacks, you may
have target creature defending player controls untap
and block it if able.)
Undying
What a pain.
