added miracle ability.

i choose to use other cost instead of creating a brand new cost type.

otherrestriction determines if the card is the miracle for the turn.

[card]
name=Devastation Tide
auto=all(*[-land]) moveto(ownerhand)
other={1}{u} name(Miracle)
otherrestriction=miracle
text=Return all nonland permanents to their owners' hands. -- Miracle {1}{U} (You may cast this card for its miracle cost when you draw it if it's the first card you drew this turn.)
mana={3}{U}{U}
type=Sorcery
[/card]
