Dune,
I liked all the decks you posted for the
cards I suggested. I didn't bother to respond
because nothing I could think of would
improve upon what you had.
With that being said, here are a couple more
cards to try en`break.
1. Lim`Duls Paladin
(probably something w/Squee)
2.Magistarte's Scepter.
This is an idea I had for a casual MS deck:
4 Tinker
4 Counterspell
4 Trickster Mage(untaps stuff)
3 Stroke of Genius
4 Metalworker
4 Voltaic Key
4 Eye of Ramos
4 Grim Monolith
3 Magistrates Scepter
2 Phyrexian Colossus
1 Urza's Blueprint
1 Karn, Silver Golem
14 Islands
4 Crystal Vein
4 Saprazzan Skerry
