pick up a game called “The Mind”. It has 100 cards with the same back, each has a number from 1-100.
You can make a table for yourself where 22 cards correspond to major arcana, and then each set of 14 cards beyond that corresponds to a suit.
To make it easier for yourself you could have 1-14 be wands, 20-34 be cups, 40-54 be swords and 60-74 be coins.
Then use cards 78 - 100 correspond to each card in the major arcana.
