It really depends on the battle and your level. Once I got scarecrow (and later Call of Khrulhu), I really didn't bother with anything else. If you buff it right, its a great way to one shot mobs and heal yourself. I have two different decks. One for regular fights and one for boss fights. The main difference being the inclusion of feints.
If you would like some assistance, it would help if we knew what level you are, what deck are you trying to set up (mob or boss or both)? Are you soloing or playing with friends?
For the most part, you should only be using drain spells. Wraith and Scarecrow for example
My L110 Death
Mob deck: 2 death blades, 3 Scarecrow, 1 Stun Block, 1 Sharpen Blade, 3 Epic, 1 Reshuffle. My TCs consist of only TC Death blades.
Boss deck: 3 Stun blocks, 2 Death traps, 3 Death blades, 2 Feints, 2 Scarecrow, 1 Frankie, 1 Wraith, 2 Spirit tri-blades, 1 Sharpen blade, 1 Spirit tri-trap, 4 Epics, 1 Reshuffle. TCs consist of 2 Death traps, 2 Death blades, 2 Spirit tri-traps, 2 Pierce, 2 Feints, 2-3 Cleanse charms
Well I just got Frankenstein, and I need a deck for both, I usually forget to switch decks, and for the most part I am soloing
For the most part i use drain spells... Scarecrow was my favorite until i got lulu.. anything that adds health back to you is a must in my opinion. blades/traps/faint are also good to have on hand
