I think it's a cool idea, but it's too repeatable. Dwarves like exerting effects, and so I would probably look at a card like this:
Well Armed ![Dwarven [Dwarven]](https://lotrtcgdb.com/forums/Smileys/classic/dwarven.png)
Condition • Support Area
Maneuver: Exert a Dwarf to play a
![Dwarven [Dwarven]](https://lotrtcgdb.com/forums/Smileys/classic/dwarven.png)
possession from your hand.
Or I might make it regroup to minimise its potential for choke. Or perhaps it should cost
![1 [1]](https://lotrtcgdb.com/forums/Smileys/classic/1.png)
or

and discard for the effect.
Also,
![Dwarven [Dwarven]](https://lotrtcgdb.com/forums/Smileys/classic/dwarven.png)
tends to deal mostly with the discard pile and it's a shame that this card doesn't.
Ket's most recent offering is a different direction, but also a very interesting
![Dwarven [Dwarven]](https://lotrtcgdb.com/forums/Smileys/classic/dwarven.png)
ability.
