Oohhh I get it now. So seers and mages can’t necessarily change with magic, they only know things ... with magic. But they can use there knowledge and will to change outincomes that they don’t want. Ex. A mage of light receiving a vision of some important event than changing the event to fall into there favor by doing it themselves. Or with the coin flip thing they can’t really influence the luck itself but maybe the factors leading up to the coin flip so it CAN fall in there favor.

Exactly! That’s my thinking when it comes to the Mage/Seer Witch/Heir conundrum at least.
