Intro
The basically game machined is health bar and defense bar, if you known this idea then most of the game won't be obstacle to you.

the whole game your whole team is sharing the same health bar, it's really weird and personal never seen this kind of design even in the mobile game.

combat part

• keeping your defense so enemy won't deal too many damage to you, don't need to put in much just need one or two defense card is enough.
  
• the caster skill would apply a strong debuff lower enemy defense and gain weakness.
  
• some card could use even you used all action point, this kind of card like the Unstable barrier, you still gain 3 defense even when zero action points.
  
• some heal card would gain more effect when discard your hand cards, like the heal card Quid pro quo it's really useful when you team is lower hp.
  
• lower points cost card like 1~2 points not that bad when you could stack many of them then one shot kill enemy.

dungeon explore part

• fill up your hp bar in any meaning way, this the most important thing you need to do, especial when next enemy is elite or Boss.
  
• since the team didn't have front or back of team composition, so all you care is gather more card instead of found new hero to your team.
