Very coo! THANKS so much for posting.
It looks like you were on the right track. I will try to clarify one minor point regarding the turn sequence --
Start of Turn
1. Decide which side will activate first.
2. Activate the first character on the chosen side.
3. Draw and play a Solo card on that same character. (Note - this is not optional. The first card is automatically assigned to first character to activate.)
4. Resolve the card and then resolve the character's activation.
5. Activate the second character on the same side.
6. Draw and play a Solo card on the character you just activated. (Note - you do not pick a character. The second card is automatically assigned to the second character.)
7. Resolve the card and then resolve the character's activation.
8. Activate the third character on the same side.
9. Draw and play a Solo card on the character that just activated. (Note - Third card goes on third character)
10. Resolve the card and then resolve the character's activation.
11. Activate the remaining characters on the same side....
As you may have discovered, there are Solo cards that will mix this sequence up. But this is the way it will normally flow.
Apologize for the confusion. I hope this helps.
HAVE FUN
