Optimal Combination for Character Deck Card System for bossing

From my understanding there are 2 decks.

Well basically, my rationale was to have a balance of damage and survivability.

Deck 1

1. Demon Slayer - reduces status
2. Paladin - increases damage
3. DK - 5% hp

3 Warriors bonus - adds 10% hp

Deck 2 - Not too sure

1. Marksman - adds to crit
2. Bam - reduces damage
3.Bucc - adds damage?

Are there others better combination out there?
Was wondering.
