Rube Goldberg Chain Reaction

Recently, I had an idea for a deck. Create a board setup, do something innocuous, then let that action create a chain reaction that leads to the death of one or more players. My personal criteria is the reaction should consist of nearly no optional actions between the initiation and completion.

My current incarnation is this:
In play: Last Laugh, Stalking Vengeance, Boggart Shenanigans, and two 1/1 Goblin Tokens.
In graveyard: Crypt Champion, Mogg War Marshal.

Cast Torrent of Souls, targeting Crypt Champion, which reanimates Mogg War Marshal.
Crypt Champion dies. Last Laugh and Vengeance triggers for 1 damage to all and 4 to target player.
The two original goblin tokens (now 3/1), the Mogg War Marshal, and a 1/1 goblin die from Last Laugh. 4 damage to everything, additional 11 to target player.
1/1 goblin token from Marshal dies, 1 more damage to everything, 1 more damage to target player.
Stalking Vengeance dies, 1 damage to everything.

Total damage? 23.

I think it looks hilarious. Now, here are my problem.
1. I need to build a deck that can actually achieve this board/hand/graveyard state.
2. I usually play 2HG variants, so 40 damage is preferred. Adding more goblins to the initial state is the obvious, and probably easiest solution, but why settle for mediocre? Which leads to...
3. Can anyone expand the combo to make it cuter, i.e. more steps with minimal additions.
