Deck built around
Katra, the Devoted, and mainly effects concerning lifeforce / bolster.
It stays a casual themed deck (not specially a strong one), I think you can reach gold with this one. However, it has the advantage to be an easy deck to understand and to play.
If you don't have cards from some campaigns, check the sideboard to replace them. ^^
How to play it
Play cards, then play effects gaining health, and attack only when you have big monsters.
Some nice tips:
Nice beginning hand is when you 1 health gaining proc + 1 creature boosting on health proc.
All cards can be cost with 2 time and 2 shadow influences.
To reach 4 times is nice only for Curtain call.
Condemn proc Bolster (and Lifeforce) at opponent turn, use it at this moment preferably.
