Looks fun, but all the special effects seem like they'd be hard to remember. I wonder if there's a simpler variation that requires fewer rules to remember.
You could also use mnemonics to remember effects, I've come up with these:
2 - Two blue (counterspell cost in Magic)
3 - Three Wishes (wish for a card from stockpile)
4 - _ (possible connection: 4 is "Death" number in China and Japan)
5 - Dig for more cards (with your 5-finger hand)
6 - Six sweeps the tricks (thanks to ChatGPT for this one)
7 - Lucky Draw
8 - Pair of Glasses
9 - Lasso (you bind opponents card for a turn)
10 - Highest points (no effect, should be easy to remember)
J - jump (sudden assault)
Q - Mom steps forward to protect her kids
K - One king's on scene, you need fourteen. If two kings defend, make it ten. With three kings on the rise, try seven to prize. When all kings alive, you just need five. (thanks to Claude for 1, 2 and 4 kings)
Ace - Ace clears the space
