I can only try Daarg Deadblast lv1 because the lv2 rental price is quite expensive in my opinion. Combine it with Baakjira and Scavo Hireling can immediately provide a difference in SPEED by 3 points. Unfortunately, with only 2 points of Attack power, it will feel lacking if the opponent uses units that have VOID.

For Rage, I really like this unit even though I can only rent its Lv2. It has 4 points of Attack Power, at least that's enough to hurt units that have VOID. I like to combine it with Runeseer Sevaya Lv3.
