Which cards are your favourites? I have set up the following categories:

1. Hero unit

2. Non-hero unit

3. Support card

4. Tactic card

5. Quest card

I don't have the cards yet, but a preliminary favourite for category 2 non-hero unit is Savage Marauders . This is the only unit with a Cost of 3 and a Power of 2! They can be played in all zones and are therefore very useful for all strategies.

Right now I'm leaning to a corruption-heavy strategy so that may be influencing my choices somewhat.

Festering Nurglings

Urguck

Shrine to Nurgle

Seduced by Darkness

Infiltrate!

Keystone Forge

Mountain Brigade

Master Rune of Valaya

after that I kind of run out
