{w/u}, {t}: Draw a card. Then an opponent may pay {1}. If they don't, repeat the process.

{w/u}{w/u}{w/u}{w/u}{w/u}: Search your library for a card named Rhystic Study and put it onto the battlefield tapped.

{w}{u}, {t}: Create a token that's a copy of target card you control named Rhystic Study unless each opponent pays a combined total of {2}. Activate only as a sorcery, and only once per turn. (Any player may pay part of the cost. If the total mana combined that opponents spent was exactly {2}, counter this ability.)
