Event chest this week

I am curious hoe the event chest works.
For example this week. Do you have a higher change te get broken spire troops such as sheggra this week since gobchomper is a troop from broken spire. Or only a higher change of getting gobchomper?

Got seven Stone Giants from ten chests, so I would say: definitely yes.

It is a higher chance to get all of the weekly kingdom’s troops. I used 22 event keys and got a Sheggra and 2 Broken Sprie epics. Aside from the few traitstones, I believe only 3 troops weren’t Broken Spire.
