Red Rush (Mountain light) (video)
This red rush deck is far faster than most similar ones and you can more consistently get the required lands you need in position. The reason for this is simple, all the creatures in this deck can be played with only 1 mountain, with hate seed and firebringer being the exceptions, but you dont want to play them early anyway. The game plan is to play neutral lands until you get the sweetspot at the opponents well. Mulligan for neutral cards and focus on developing lands. See the video for more information.
