Optimal Combination for Character Deck Card System for bossing

So basically the ideal case would be

Deck 1 - 1 of them level 200 with the rest level 120

1. Demon Slayer - reduces status
2. Paladin - increases damage
3. level 120 bucc #1 - increases dmg

3 Warriors bonus - adds 10% hp

Deck 2 - With 1 of them level 200 and the others level 120

1. Marksman - adds to crit
2. Dk - 5% hp / lvl 120 Paladin #2
3. level 120 Bucc #2 - adds damage?

Alternative Deck 2 - If soloing Empress using Phantom

1. Evan - lvl 120
2. Aran - lvl 120
3. Bucc - lvl 120

Because Buccaneers are definitely Warriors.
