Changelog:

- Added a new character: Pi!

- Added 6 new cards.

- Decks now can only have 3 copies of each cards instead of 4. (So all your saved decks will be deleted, sorry for this.)

- Filters in deck builder works different, now clicking on them will only show that type of cards, once at the time.

- Added minor animation when clicking on buttons.
