The Holy Grail

Indestructible
{1}, {t}: Add two non-black mana in any combination of colors to your mana pool.
{w/u}{u/r}{r/g}{g/w}, {t}: Search your library for a Servant creature card that does not share a Servant type with a creature you control and put that card onto the battlefield. Then shuffle your library.
The True Grail contains all of our hopes and wishes.
