INN - M13 - RTR - M14 Standard
1 drops - Cackler is a staple and Stromkirk Noble rounds out the 1 drop suite as the only other option really. Foundry-Street is the alternative, and while it's easier to trigger, the upside of it working is smaller. Noble is also helped by the 9 burn spells maindeck along with the 3 Madcap Skills.
2 drops - Ash Zealot because it's one of the reasons you go Mono-Red instead of G/R. There's also a Burning-Tree package, which is a little lackluster since it only works with Firefist creature-wise, but it can also give something Madcap Skills, drop a 1 drop, or burn a guy out of the way.
3 drops and beyond - Boros Reckoner is a good man. Hellrider is also a good man, but there's only 3 of him, because we only run 20 land. Thundermaw is here because we hope to mise and draw it as our late-game punch.
Burn Spells - Voice isn't as omnipresent, so Pillar isn't so great. Searing Spear seems good with all the Jund running around (Olivia + the occasional maindeck Vampire Nighthawk), and Brimstone Volley is in because 5 damage is a lot (though there's only 3 since they're somewhat mana-intensive).
Mana - One of the most common ways we die is flood, and Mutavault stymies this by giving us something to do with extra mana and becoming a creature when its role as a land is irrelevant. However, we don't need to draw Mutavaults for a while, since we're almost always going to have something to do for the first few turns, hence the 2. We also don't want to hurt our chances of T2 Ash Zealot or T3 Boros Reckoner. Hellion Crucible is simply too slow and mana-intensive, and given Mutavault's existence, its downsides far outweigh its benefits.
Sideboard:
4x Burning Earth - A given with all the 3 color all-nonbasics decks running around.
2x Electrickery - For Naya Blitz and token variants
3x Flames of the Firebrand - For token variants and aggro mirrors (aggro mirrors can get very grindy, so the occasional 2 for 1 it provides is great)
4x Volcanic Strength - Wrecks aggro mirrors, since aggro decks really only have access to damage-based removal. Suiting up a guy either creates an inevitable clock or a mighty blocker.
2x Pillar of Flame - For Strangleroot Geist/Voice of Resurgence/Geralf's Messenger/Xathrid Necromancer
The Maybes:
Pyreheart Wolf - Because Ari Lax
Foundry Street Denizen - A more consistent '2 power' guy than Stromkirk
Gore-House Chainwalker - Just a solid aggressive 2-drop. It's too vanilla for the deck though
Stonewright - Good in the mid to the late game, though awkward in the early game, which is when we want to be doing stuff
Mogg Flunkies - It's Watchwolf
Lightning Mauler - Haste is nice to enable Battalion (though Ash Zealot already plays this role like Flinthoof Boar in the Gruul Version). Giving a Boros Reckoner haste seems alright as well, and if Pyreheart Wolf ends up in the deck, giving that haste seems sweet as well
