Got Isolate recently and wanted to try it. Every three times I tried to use it (PW: Teferi Hero of Dominaria, lvl 60) it resulted in a softlock. Both while trying to exile tokens and normal creatures. Didn’t try with supports.
Works fine for me
Just tried again, softlock again.
What effect did it have in your match? In your screenshot there’s no effect in the log.
Exile never gets recorded (but it has been requested as an update to the log). I don’t recall what it exiled.
Since this is a recurring issue for you, make sure to update this post with these details. Recordings help a ton.
