I've got this casual mp deck that I'd like to try at a local store's Monday night extended tourney. The thing is, Sol Ring's are crucial to getting the deck off and running in any sort of timely fashion. It doesn't matter so much with my friends, as we play mp-chaos almost exclusively, but for duels I think it really needs the mana boost. So, any suggestions for replacing the Sol Ring's to make this deck extended-legal (and hopefully without losing too much tempo), plus any general improvement suggestions will be greatly appreciated. I know the deck is ten spells too large, but it does run pretty well even so. Decklist: Creatures: 4x Beast Attack 4x Elephant Ambush 4x Roar of the Wurm 4x Crush of Wurms 4x Call of the Herd Spells: 4x Muscle Burst 4x Sylvan Might 4x Overrun 2x Parallel Evolution Artifacts: 2x Mirari 2x Catalyst Stone Mana sources/searching: 4x Deep Reconnaissance 4x Diligent Farmhand 4x Sol Ring 25x Forest Thanks!
