Man, I love how every time I post decklists on here I just get straight up ignored. #feelsgoodman
LOL, I know how you feel. I had to go to another thread and solicit Barney to try my deck out and give me feedback. I would suggest using either [ deck ] cardnames and amounts [ /deck ] without the spaces in the brackets, or [ c ] cardname [ /c ] for each card. either way works, but it allows people to see the cards in the deck so they aren't going off memory or don't have to look up card's they're not familiar with.
That said, here's a few thoughts I have without playing the deck. I'm not sure you want Endbringer and Big Chandra in a deck with 23 lands. It's going to be hard to hit 6 lands reliably on t6, you're probalby already using the looting/draw in the deck to hit 5 so you can play Glorybringer/Reality Smasher on curve. BTW, good call on Reality Smasher, I'm going to have to consider him for my mono-red as well. Not sure that including enough colorless lands to support him is worth it since we're only running 23 lands though. I guess i'm just saying you have a really high curve for only 23 lands.
It almost seems like you're trying a Red Ramp deck with Conduit of Storms and Vessel, but I'm not sure those slots are worth it. And I'm not sure what Mirrorwing dragon want's to do in this deck. You don't have any combat tricks to copy. I think you want 4-6 one drops and the rest 2 drops instead of those 7 cards. This deck looks like it want's to be aggressive enough that it can end the game with a T5 Dragon/Eldrazi, but you're not creating enough pressure T1-3 to do that.
And I'm not trying to dismiss or belittle you, but you only have 8 posts, how many decklists could you have posted that got ignored?
