this is just a suggestion for ml kawerik as he fell of the meta and he is so hard to pick right now
1- make his s3 immune to resets while s2 is avaliable to keep him balanced while s2 is resetable 
2- s3 gives a special immunity to the unit in the back and give a new name undisplablle (mediator) or something like that and other units get the normal immunity and attack buff also the unit in the back can get the normal attack buff as well
