With the new guaranteed double tp you can so some interesting things with a Stegadon. Does that include casting slann spells from him?
No variation of the Stegadon can cast. But the push move the Stegadon can do could be used, and is being floated around quite a bit.
Yeah unless they change the keywords, only the EotG is a skink hero and thus can be used as an arcane vassal. The normal Stegadon can't.
