Inspired by a line by Toddrew in another thread I give you: The Shaman.
Until a roguish shaman-like lore master is developed which allows any card to be played out of character at cost
Each level of Shaman reduces cost to cast out of character Lore by 1 (by level 3 you can cast any card at face value).
Shaman has no spells of their own
Lore decks are built as normal based on the rest of the Lore council, once normal method has been completed shuffle all remaining lore cards and add a random selection based upon lore level of the shaman (1- 3 cards, 2 - 7 cards, 3- 12 cards) and add them to the lore deck carry on as normal
