iMtG Server: Gathering

My current Competitive Standard Deck. Opinions? Suggestions? All feedback is appreciated, thanks!

Flame Born Delver 75 cards, 15 sideboard 8 {Mountain} 8 {Island} 4 {Sulfur Falls} 20 lands 4 {Snapcaster Mage} 4 {Vexing Devil} 4 {Delver of Secrets} 2 {Phantasmal Image} 14 creatures 3 {Pillar of Flame} 3 {Shrine of Burning Rage} 4 {Runechanter's Pike} 4 {Thunderous Wrath} 4 {Incinerate} 4 {Bonfire of the Damned} 4 {Ponder} 26 other spells Sideboard 1 {Pillar of Flame} 4 {Mana Leak} 3 {Turn to Frog} 4 {Ratchet Bomb} 3 {Arc Trail} 15 sideboard cards

Why four pikes? I'd say drop um to two or as a one of and put more dig into the dek with things like {thought scour} or {think twice}
