Always cool to see a new face around these parts!
Glad C3G inspired you to launch into some creativity of your own!
A few "pro-tips" for you for your cards (I just looked at the first one):
1. Use all caps in the left box, with the character name and secret identity, and with the power titles.
2. If a power is a special attack, the title should end with the words "special attack".
3. Always aim for clarity. What color are the Ki markers? For Ki Level 3, do removed Order Markers have to be revealed or unrevealed? (This will change how the power plays).
4. You can use short hand, but don't use sentence fragments.
In the special attack, if you don't want to spell out the title of the special attack, say "this special attack" rather than just "special attack."
5. Just to get you started, here's how I would reword the second power to make it sound more "official":
DOUBLE SUNDAY SPECIAL ATTACK
Range 6. Attack 5.
Before attacking with this special attack, you may remove any number of Ki markers from this card. Choose one figure to attack for each Ki Marker you removed this turn. Roll attack dice separately for each attack.
