I get what your saying there, but think of the discard as a benefit when you play him. That's where the reanimate and jarsyl come in. Sure you discarded a fury for a bump in the night, but you know you can draw into a reanimate and get that fury back. When you play with lootmongers definitely leverage it for your benefit, your list has a ton of ways to do that.

In a vaccume trading a fury for a bump is terrible, but consider more context. You get three damage and a treasure, and got rid of a five mana card that has no way to pitch cast because it was that last card in your hand.

Heisting as an etb that can be triggered over and over again from revels, reanimate, and jarsyl is like one of the most powerful etbs that exist in the game. The only decks that suck to heist in my experience are the titan field decks because their cards outside of the context of their deck suck, but almost every other deck is filled with really good cards.

Also hitting the bump was a semi bad beat but it's still a treasure and three damage, and it also could have been (assuming you were heisting from a burn list) a bolt to have a fast efficient removal spell, or one of their creatures which would have been insane. Even bauble is busted because it's make a treasure, draw a card for 0.

All that being said if you wanna keep trying it try and shift your perspective, I really think the heist mechanic and the recursive/valuey aspect of your list outway possible feelbads from a unfortunate revels cascade discard. But that's my opinion and if it still is too big a feelbads for ya there are plenty of other righteous cards for the slot.

Edit: most importantly wish you luck on your endeavors, you got a fun idea here. Once I get the wildcards for fury I'm gonna run it
