Believe you should find a way to add Collective Defiance to main deck to handle kalitas and other 4 toughness threats. It allows you to keep the pressure on your opponent. Also Hungry Flames works the same way while also being at instant speed for 3 to a creature and two to your opponent. I run RDW with 16 main deck burn spells here's my current list. My deck:

RDW Burn Edition

Standard Atroxreaper

Atroxreaper, both are very good suggestions. I actually forgot about Hungry Flames so I'm going to try to find a way to work that in. I probably won't use Collective Defiance only because it is about to rotate soon and I wanted to make this deck rotation proof. Thanks for the suggestions.

I feel ya im going to miss collective and incendiary flow and need a replacement for falkenrath gorger.

Might main deck Abrade and run Flame Lash

I feel like Abrade is a must run in any red decks right now just because it can destroy artifacts. I feel like that's the only thing you can do to deal with any of the gearhulks if you run into them.

So far my opponents have been dead before I've had any gearhulk issues I've been keeping my abrade in sb.

I gotcha. I guess it all comes down to what is in your local meta. I've had some issues with gearhulks a couple of times so I feel like I need to run them.

After rotation I may just move them into main unless they print a 2cmc 3 to player or creature. I feel open fire is too slow.

They are reprinting Lightning Strike another amazing burn spell.

Yeah I saw that. I'm pretty excited for that coming back because I wasn't playing magic when it was in standard. It'll definitely be making it's way into this deck.
