This paint your own set of MOPEW cards is not based on traditional
artwork styles, but on a mix of the MOPEW deck and Earth convenctions.

The values on the cards are written in common duodecimal_ digits, using
↊ and ↋ for ten and eleven respectively, and the orders of magnitude are
treated as a sort of suite, with artwork based on different shapes.

To get a MOPEW set, print two of each triangle, square and hexagon card
from 0 to 11, and paint them in a warm colours scheme for the Earth deck
and a cool one for the Heavens deck.

The additional S card can be used to get 13 cards per suite and use the
deck for common cards games.

The extra “circle” suite was designed as the back of cards, but numbered
ones are available because it was low effort making them, and could be
used as an alternative to the triangle ones.

When painting the cards by hand it is recommended to avoid painting the
backs, as it would be hard to make them identical to each other.
