Pure Red Valakut Meltdown

this is the deck i was planning to build, ive already tested the deck using proxies and it runs well. its planned to be a budget deck, so not much high value cards. it played good though i havent tested it yet with fast aggro decks like goblins or white weenies. the strategy is straight forward burning creature and opposition player. i use the fiery fall and the igneous pouncer for mountain cycling. so that ill have enough supply of mountains for valakut and for earthquake and fireball. i have no idea for a side board yet. comments please.
