So being a large fan of all things Clamp, I decided to make a class that relies on some of the strongest magic in their universe. I made a cardcaptor class. It works best if you have a clow deck. But a deck of cards works as well.

Just make sure it's only available when you've made up a storyline not even you understand.
At least it had an ending. A fruits basket campaign would have no conclusion.
The card captor character would have a mentor who they only know from legend, who will show up at near epic level so they could take over their job freeing them to be a baker. (spoiler confused with an in joke). ;)
1st: Craft cards, Create power card
The The card Catcher, or whatever, starts with 3 cards, utility, combat, and monster. They can find more cards in an adventure, or capture a monster, magical effect, or natural event.
Craft cards can make mundane cards, but the empty power cards need to be worth 100GP per level each. 50GP min for cantrips. The character starts with 3 empty power cards worth up to 1st, second, and 3rd level. They can use gem dust or monstrous squid ink to up the value of a card.
Create Power Card allows the card catcher to capture a monster, magical effect, or natural event. The target whatever must be below or equal to the level of the card. If the target is already defeated or somehow held, the capture is automatic. Otherwise, it's a mental contest, with the catcher rolling their mental strength, Int., Wis., Cha, 1/2 levels, +1D20 vs the targets power. The targets power is Int., Wis., Cha.,(If mindless use Str., Con., Dex., or challenge rating) +any dice of damage it can do, + 1D20.
The Card Catcher has spell slots equal to a sorcerer's spell slots. They may have power cards too high for them to use, but they have use magic device as a class skill for such situations. Failure to use results in the thing in the card running amok for 10 minutes.
I knew that deck would come in handy some day.
This would be a good fit with mythic.
You could make an artifact power card, and someday trap the Terask.
Your familiar would be a card monster, that would teach you all about the magic. A tiny, winged, lion would actually be a good familiar.
