You can see that your troop is far weaker, unless the splash radius is something like three tiles, where it would deal double damage.
In my opinion, you need to significantly increase the damage (to 70 or something), and make sure it targets an area where it gets the most coverage (much like valks).
I am comparing it to the dragon because they are both flying, 20 spaces.

Also, I forgot to add that the DE cost is probably far too much: the golem takes up 30 spaces and costs 450 DE at level 1, and the witch, which (get it? ) costs 250 DE per 12 space, costs 500 DE for 24 space at level 1, still less than your troop.
