Aldor

Flash, Hexproof
When Aldor enters the battlefield you may target
an instant or sorcery spell. If so look at the top 6
cards of your library, you may reveal a card, if the revealed cards converted Mana cost is equal to or greater the target spells converted Mana cost you
may choose new target(s) for the spell. Put the revealed card in your hand and shuffle your
library.
