I'm rather fond of the ability that says,
"You may play Magisterium any time you could play an instant if you pay

more to play it."
Of course, possessing that ability may require it to cost more anyhow. (See that [card]Rout[/card] costs

more than [card]Wrath of God[/card].) I guess the question is this: Should this card cost


all the time and be playable at instant speed or should it cost


normally and have the additional cost to play it at instant speed?
