Search your library for a archangel, shuffle it, put
the archangel in exile.
That creature gains unseal X(if this permanent
is put into a graveyard or is exiled. Exile it with X
seal counters on it. When all seal counters are removed
it reenters with X +1/+1 or loyalty counters on it.)
X = current unseal value.
It also gains while this creature is exiled and 2 or
more lands enter under ur control. Drawl a card
and remove a seal counter from an exiled
archangel.
