MTG Red deck suggestions?

The deck has a good foundation, but you may want to add some more lands (just a few more to optimize your chances of getting the lands you need. Maybe go to 23 or 24 tops). Also, because this looks like a burn deck, you may want to throw in a few Shrine of Burning Rage. It's an artifact that at the beginning of your upkeep and whenever you cast a red spell, put a counter on Shrine of Burning Rage. You can sacrifice it at any time to deal X damage to target creature or player (X = number of counters on it). I would throw in 4 of them if you can get them. Those might help a lot. Also, you may want to add Arc Trail (x4). They cost 1 and 1 red to play, and you deal 2 damage to target creature/player and 1 to another creature/player. If you don't want them in your maindeck, you probably should have them in your sideboard, because they are insanely good against illusion decks (all new illusions have the effect: "if this card is targeted by a spell or ability, it automatically dies"). Another good red spell you probably want is Brimstone Volley. It deals 3 damage to target creature/player, but if a creature died that turn, it deals 5 instead. Some really good red creatures are Falkenrath Marauders and Stromkirk Noble. If you want a big creature, there is always Flameburst Dragon. He is really good, but if you add him, will definetely want to up your land count to 24ish.

It was probably a longer answer than you wanted, but I hope it helps. :)
