I built my Lost Souls deck for PvE, yet I didn't like them for PvP as much, preferred pure Shadow on that matter. I'd go , because I felt an agressive presence felt better at T1 at most of the PvE maps. Still had a LS testing deck for PvP, but it never got as funny as pure Shadow, in PvP that is ^^
Shaman was crucial for me at my Nature / Stonekin decks at T1. The healing was nice, and coupled with Surge of Light they would keep my Windweavers alive for a long time. It'd carry to T2, and although they'd be weaker than Crystal Fiends, they'd save me enough Void Power to carry to T3 in most BGs
Shadow is awesome in both PvE and PvP. I miss making gimmicky soul storing-based decks for the sake of playing with Soulsplicers, Furnace of Flesh and stuff Nature is really strong too, as the heals are awesome if you've got a nice army going on. But my heart stays with LS / Stonekin, even though the Stonekin deck is a bit too slow to play in my opinion
Everything is text format in this thread, Eirias' post on it looks like it should, with bubbles and stuff. I guess it's because some changes were made to the forums since this thread's quite old
