Well Lewis has obviously tested his deck, and I haven't, however it's anything but "standard" card choices.

First and foremost I'm not sure I see the point of white with only 2 Plows. He admits Merfolk is a tough matchup, running more spot removal would help with that.

Random Isochron seems like a good idea actually, but Deed + Wish in the same deck is definitely new... or it's so old we've forgotten about it.

Tempest of Light in the wishboard is funny, but how often do you really run into Enchantress? Tsabo's Decree is even funnier, but aren't you already in a pretty good board state against tribal if you can resolve a 6 mana spell?

I do like that he has outs to Iona in every color, and several ways to deal with Shroud guys. Perhaps the best argument for keeping a white splash is the psychological effect of the Reanimator player seeing a Tundra, automatically assume 4 Plows, and name white w/ Iona.

Are 2 Loams necessary? Seems he might be overvaluing wastelock, and you never want to draw a second.

He says he wants to fit in a 4th Jace, but, I think some more 1cc spot removal or Edicts would serve the deck better.

Heck, what do I know, I'm just a goober on a message board.
