eruth and thalia
Eruth, Tormented Prophet Bug casting Thalia
When, instead of a draw, Eruth, Tormented Prophet exiles two cards and one of those cards is Thalia, Guardian of Thraben, it seems Thalia costs three mana to cast instead of two. This might be the case all the time, or it's possible that having Katilda, Dawnhart Prime in play is a factor, too.
