It won’t see competitive play for sure. In order to see competitive play, it needs an easy way to get rid of its own deathrattle and that requires a 2 card combo. It’s just not worth the space just so you can yoink 1 minion. You’re better off just running removal and killing the minion you want to control.
And if the minion is full of buffs and other nasties, you’re better off just running Nameless One which does the job 10x better.
