Here's a peculiar spin on triangle decks from James Ernest's Pairs and Great Dalmuti. I think I've talked about this before in another form, but as a mix of suits and ranks. When it's just numbers, I find it fascinating that all the cards divide up 19 in different ways. When two numbers are high, the third is low. The most balanced cards get are 6 6 7.
What would you do with this deck?
