Would love suggestions!!! However, I want to stay mono red - and no not want to invest in duel lands. I've tried a R/B version and a R/B/U version and was unhappy with playtesting. Mono red seems really consistent and fun - the deck is extremely budget, under 10$ if you take out [Chandra, torch of defiance] - she isn't necessary but she does prove to be useful in almost any matchup. She can top deck you combo pieces, act as removal if you need it, or just be a straight up win-condition.
MainboardThis decks main combo involves Pia's Revolution and
Ravenous Intruder
in order to sac artifacts and give your opponent the choice to give it back or take the burn.
Ravenous Intruder
after buffs - can get in with lethal 2 major ways. You can make him unblockable with Key to the City or turn him into a massive burn spell with Fling
Scrap Trawler adds a ton of value to your combo, making it so even if the other player opts to take the 3 dmg from Pia's Revolution you still get to fish something out of your graveyard. Like Implement of Combustion or Ornithopter and keep your combo rolling. Even if Pia's isn't out - he is just a good card to have out in this kind of deck.
Chandra, Torch of Defiance helps us fish out our favorite pieces a bit better - all the while either buffing up into a more solid win-con / or being able to remove threats that might otherwise kill us.
Reckless Fireweaver is our go to early game drop - works well with just about everything in the deck and adds a ton of value to all the artifacts we are droping/ sacing and replaying. Honorable mention to Servo Schematic our fireweaver makes this card amazing.
Hope of Ghirapur seems like the best one drop we can ask for - 1/1 flyer that can sac itself and is an artifact. Locks our opponent down to what they can play next turn - and chance of playing the same copy multiple times in one game is very likely.
Renegade Map simply is a cheap artifact we can sac but also serves the purpose of not being afraid to keep 1 land hands. Not to mention is sacs itself and benefits from every trigger. Auto add for consistency and value.
Pia Nalaar is our backup sac outlet if
Ravenous Intruder
doesn't show or fails. Not to mention 3 mana for a 2/2 that summons a 1/1 flyer that ends up hitting most of our triggers feels good.
SideboardHijack for vehicles - take there car, use it - crash it or sac it. Either way great value.
Magma Spray and Shock to slow down a aggressive player in the early game.
Edifice of Authority and Pacification Array - a way to deal with large creatures while avoiding droping our artifact count to much.
Sweltering Suns Our board reset for early game aggressiveness
