So as you can see, the sideboard isn't the most common of options. The biggest similarity that all Living End decks should have in the board is the Ricochet Traps, which I've seen as a 3 or 4 of. So I'm going to break down here my decision making with this sideboard.
Gnaw to the Bone x3-
Living End doesn't tend to be the most interactive deck there is and burn can be a tough match-up due to them just having to throw everything at your face and nothing to do in terms of slowing you down. Accompanied by Eidolon of the Great Revel you easily end up taking 4 damage for a living end by itself. Gnaw to the bone helps fight the burn spells and gain a ton of life earlier and later in the game.
Jund Charm x3-
I've really enjoyed this card as my Graveyard hate of choice. While Leyline of the Void is good, this is much better as a blowout card in the mirror and helps as a board wipe in other match-ups. I use to have this main, but ended up cutting it to the board for number changes with the Beast Within. This helps out a lot against Infect and Boggle especially, basically giving you some more board wipes to fight against them.
Ingot Chewer x2-
Obviously to help out against any artifact heavy deck. Usually takes the place of Shriekmaw against Tron and Affinity.
Avalanche Riders

Shatterstorm

These are Flexible spots in the sideboard. I've toyed around with other things and can easily switch these up depending on what Meta I might think I'll be heading into.
Ricochet Trap x4-
Obviously to fight any Delver or counter-heavy decks. Helps push the combo through and acts as an easy 1 mana counterspell for the deck.
