Constelation — Whenever an enchantment enters
the battlefield under your control, you may pay
up to {w}{u}{b}{r}{g}. If you do, look at the top five
cards of your library. You may put one instant or sorcery that shares a color with each mana you
paid in your hand. If the name of those cards are
"Gods willing," "Ponder," "Nighthaze,"
"Blindblast" or "Explore" you may cast them
without paying their mana cost.
