some conditiondiscard and burden remove and you're done
but still a nice combo, that's true.
absolutely, its easy to stop, which is what makes it not "broken" like an Open format loop.
the burden removal though can't stop it at all. there can be 0 burdens and you can pull the loop. condition discard is rough though. and the ones that stop you from adding burdens with texts like: "if the shadow player plays a card that is about to add any number of burdens, exert this hobbit to prevent that."
stuff like that gets annoying.
but yes, a fun deck, and a fairly competitive deck.
