Phyrexian Referee

{3}{u}{u}{u}: Return Phyrexian Referee to your
hand. Exchange control and ownership of your hand and Jason's hand. If Phyrexian Referee
does not currently have a sticker, cover Jason's name with a sticker that has your name on it. If Phyrexian Referee currently has a sticker covering Jason's name, remove that sticker. (Use this effect only if you own Phyrexian Refereee.)
