Hexproof, indestructible (This artifact can’t be the target of spells or abilities your opponents control and effects that say “destroy” don’t destroy it.)

Permanents you control have “{T}: Add one mana of any color.”

{T}: You may pay {w}{u}{b}{r}{g} any number of times. When you pay this cost one or more times, exile Eight, the Planar Tree. Then search your library for that many permanent cards, put them onto the battlefield, then shuffle.
