I already have silver blades and a few dimir charms n one other syncopate. If I had better ways splash red id look but don't need red for reckoner or medics if wanted include. I like idea of silver blade be open to give the geist angel double strike tho but I think cavern of souls with all the spirit creatures is deadly. Just plan to use this deck next month in a big standard tournament and I have no idea for side board.
