Daleto, Storm Outcast

X is the number of outcast counters on Daleto.
When Daleto enters the battlefield, exile up to X permanents you control.
{t}{r/w}{u/r}{w/u}{x}: Exile Daleto with an additional
outcast counter. Until end of turn, you may play
X permanents with outcast counters on them
from exile.
Permanents with outcast counters cost X less to
cast.
