I got another heatsmith and if memory serves me right, I have been getting a number of them in the rewards chests in recent days.
Silver III has been so much easier than Bronze I was last season. Last season had many days when I just wanted to rage quit with string of losses like 5 or 6 in a row.
These days the battles are more pleasant with most battles being wins and the occasional loss here and there.
I really like the Thaddius Brood summoner. He makes quite a big difference for the Death Splinter now that he is around.
Went back to check and I now have 22 heatsmiths. That is 22 more than I need. Still haven't found a plan to incorporate them into the battle.
