This is a pretty standard Skred Red list that I'm running right now. The focus of the deck is to lock your opponents out of the game with Blood Moon, control the board with mass damage spells, and win with Koth or the dargons.
Snow covered lands synergize with Scrying Sheets and Skred.Skred, in turn, synergizes with Boros Reckoner to deal huge damage for just R. Pyroclasm and Volcanic Fallout also go with the reckoner, as it'll deal 2 to the whole board and 2 more to whatever you want, allowing the kill on creatures with toughness 3+.
All of this is to clear the way for Koth and the dragons to beat the opponent's face in over the course of a few turns.
The rest of the deck is there to fill the gaps. Lightning Bolt is, well, lightning bolt, and Magma Jet helps to smooth your draws. Mind Stone and Relic of Progenitus are there to provide some small value, and then pop for the draw when you need it.
As for the Sideboard:
Chalice of the Void: Cast for zero against Living End (or Restore Balance), and one against storm and tron.
Combust: Splinter/Kikki tech
Molten Rain: Very versatile. Use it to destroy your opponents colored sources when the blood moon is out, or use it to replace blood moon in red matchups.
Relic of Progenitus: I've been going back and forth on maining this Relic, and it seems to be a good board in for whatever isn't effective against any matchup.
Shatterstorm and Smash to Smithereens: We obviously need some artifact hate, and I tend to like the cheaper cost, instant speed, and damage of smash to shatterstorm, though I've been considering going 2-2.
Simian Spirit Guide: Board them in when you're on the draw so that you can cast blood moon before your opponent is ready for it.
Volcanic Fallout: For when you need another sweeper, and being uncounterable doesn't hurt the faerie matchup.
