Basically this is a treasure card that is in the form of a School Teacher.
Other prominent figures could be there as well, like Ambrose, can also have cards.
All cards should have base damage over 1000, and of course their element. Ambrose could be a non elemental damage (not balance) and be the highest. Even cards like Malistaire (thread inspired by that thread) would be included.
Perhaps these cards would also institute wards, charms and traps of their element.
These cards would have to be exceedingly rare, given their extraordinary power.
That can be good but teachers are wizards too.When they got card, peoples will say a treasure card for them. And then, card of monsters. And then, Nothing else i guess.
