Yellow means caution! AWESOME BUILD! Plus 1 from me! only thing im concerned about is black mana. Do you have problems getting the right land colors? if so i recommend Mana Confluence

Thanks for the suggestion Xrandox. I haven't had any major problems with mana yet. Hopefully it will stay that way. Haha

Youve got a lot of things that you want to be doing on turn 3-4 and also a lot of tap lands.

I would consider swapping some of the refuge lands out for some normal lands.

And since you have a fairly reliable source of lifelink, you could also run Mana Confluence

Thanks, good suggestion. I need to get a hold of some lol
