V'X Lord Of Judgement

Deathtouch
When V'X Lord Of Judgement enters the battlefield, look at the top four cards of target
opponent's library exile one of them face down
then put the rest on the bottom of that library in
a random order.
You may look at and cast that card
for as long as it remains exiled
and you may spend mana as though it were mana
of any type to cast that spell.
