I’ve hard cast and ability cast (Lukka) Golos, Tireless Pilgrim, and both times, he searches up the land and puts it into play under my opponent’s control.
Both instances were with Lukka, Coppercoat Outcast as the PW, so not entirely sure why that’s the issue.
Hardcasting Golos with Sarkhan Unbroken does not duplicate the bug.
Did you happen to notice if Golos damage was registered as well? I’ve just had him swinging and hitting in StD but no damage registering. Maybe a problem with the card overall?
edit. Didn’t see special support effect. Ignore my comment.
