As Jekyll

You are good, and your objective is to maintain balance. 5 vs 5 is best for you.
When passing, you need to guess Hyde's hand, and send the opposite range of cards Hyde needs.
At the first 2 rounds you usually play first, so use this opportunity to decide on the ranks.
If you have many low cards, you should let a long suit or a suit with high cards be the highest rank.
If you have many high cards, you should let a short suit or a suit with lowest cards be the highest rank.
For potion, green is best. It can exchange cards and balance cards. Do use red if something goes out of expect!

You are evil, and your objective is to maximise the difference. 10 vs 0 is best for you.
When passing, you can try to collect lots of low cards or the opposite.
You seldom have the right to decide on the ranks, so you need to guess Jekyll's hand and decide whether you want him to take a trick.
Of course, purple can push the difference by mostly 3 tricks. But red can let you take the opportunity to turn the tide if you win!
Do try to let evil progress 6 in the first round! It lets you take the control of ranks faster, and push the end of game faster.

Hyde has an advantage, since the ratio of Hyde and Jekyll winning is 3:2. However don't despair--if you follow these tips you can master this faster and reach the top 10.
