I changed my list again, lol. I'm looking at either running the new gideon over elspeth and not sure which way to go with it. Any suggestions on that? I've also splashed blue for Supreme Verdict in the main and Stifle in the side. I really like Mutavualt in here, since it's becomes any creature type. Brave the Elements has always been MVP for me protecting my guys from burn or just dying. I thought about the interaction with Exemplar and Verdict since we all know that Exemplar makes the knights indestructable, I have seen times that I wish I did have a board wipe. Since it can't be countered it makes it a viable solution imo. I was also testing out Brave the Sands in Modern with this. I got a lot of funny looks and friends were like "only you". I didn't see anything wrong with my guys having vigilance and could block more than one creature, which seemed good specially if I didn't have a Exemplar out. Here is my current list.

Thanks Nabbydain. I usually ended up taking out the *** n most games and I had thought about Skyhunter but went against it. I do have alot of removal in there for sure. At present I've put it to the side and have started trying to build a Isochron Scepter deck with Counterbalance, Orim's Chant, Counter Spell in it. It was originally UWR but I took the red out of it and added Terminus and Entreat to it. So now it looks like a Miracles deck. I gota fine tune it before tomorrow so I can play it at a SCG event here in TN. I didn't know how to put the creatures and stuff in there like u did. Thanks for that tho.

I'm just getting into playing Legacy and really like this deck. A friend helped me out on the tunning of this deck. Thinking of putting the KoM in here and the only place I can see it going is in the en-Vec slot. Most of the meta that saw were: Storm, Merfolk, UR Delver, Reanimater, and some others I didn't recognize. The en-Vec helped out because of all the Red and Black that was here. I dont have MoR unless my friends aren't playing them. Brave the Elements was a huge factor in getting me to the top 8 and then lost to Storm. Most of the time I took out the Elspeths and I will probably end up taking out the ***. Wrath helped out a couple of times but not as much. Some of the harder matches I had were Storm and Reanimater, UR Delver. I had forgotten about the KoM and I didn't really care for HoBh or KbC they normally got taken out. We had talked bout the Stone Forge in here but I didn't think it really belonged and after reading some of the posts I may end up putting them in here. Thoughts or suggestions? Thanks.
