Oracle's Orb

At the beginning of your upkeep name a card,
then reveal the top five cards of your library. If
the card named is revealed, put it in your hand
and the rest on the bottom of your library in any order, then you may pay {1}{u}, if you do,
repeat this process.

that could see the future. The oracles brought the
artificer a ball."
