Get rid of Braid of Fire. It looks nice, but errata has ruined it. Basically, at the end of your upkeep, you lose the mana it gives you, it's only good for casting things with flash, casting instants, or paying for cumulative upkeep costs, during your upkeep.

Destroy target land. Add {R}{R} to your mana pool.

Oh, i just rememberd another land destroy card you may want to look into. I think it's called Seismic Spike or somethin... don't quite remember. Anyways, it costs 2RR. Destroy target land, add RR to your mana pool.

This is kinda the way i make sliver decks :P ALL THE SLIVERS!!!

I know, it's not my actual sideboard. It's just cards that could go well in the deck that i want to know if i should put them in the deck, if i do, what should i take out. U get what i'm sayin? :P

My sideboard is cards i have that are decent :P

So, how well does this deck work? i've been trying to make a boros deck and haven't done too well... In my oppinion, Boros is the hardest guild :P maybe i just suck at it though http://www.mtgvault.com/blackrazz/decks/first-boros-deck-help/

And add in Avacyn Angel of Hope and you're set =D I also like Silverblad Paladin, Serra Avenger, and Nearheath Pilgrim. Oh, and Chieftain en-Dal can be nice. And Reveille Squad. But now i'm just going crazy :P too many awesome cards. Oh, take out 4 plains and put in 4 Seraph Sanctuary's. And finally, Pacifism is a great card in any white deck.

Voracious Dragon. Eat your goblins and deal tons of damage =D

I personally don't like the gatekeepers much. I'd get rid of them and put something better in. Idk what :P oh, and maybe a door to nothingness, just as an alternate win. =D

Get rid of volcanic hammer. It's not very good. Destructive Force would go well in the deck. Each player sacrifices five lands. It deals 5 damage to each creature. costs 5RR

Wow. I love the deck. Very Nice. Firemind's Foresight and Nivix Cyclops could be nice too. Or that other Izzet card, whenever you cast a spell you may switch it's power and toughness. It's a 1/5 with flying.
You should look at my slumbering dragon deck and help me out w/ it

I like it. Very kool. Hey, could you take a look at a deck of mine, i'm trying to make it better, but not quite sure what to do next. :P

I only put 2 in my mill deck. I personally would put a third in mine, but i don't have a third XP

Prismatic Omen
Coalition Victory
Maelstrom Nexus

Nope, its free

Definitely Need Jace. Would you mind taking a look at my slumbering dragon deck? i'm trying to add green into it, but am not sure what to add (look in sideboard) http://www.mtgvault.com/blackrazz/decks/attack-me-i-dare-you-help/

It's a computer program where you can beta test your decks vs AI's.

I play-tested your deck on Forge. It works prette well as long as you get Prismatic Omen. You could also try adding in Chromatic Lantern. or that card that costs 6G: search your library for X basic lands where X is the number of lands you control and put them into play tapped.
