I have 3 versions of the deck that I have been testing.
The first I call combo - it is the usual list of but no Mental Misstep and no Flusterstorm just the 4 Force of Will.
I played some draw sevens and go for a very fast win. This version loses to artifact hate but races most decks. I had some weird loses to Humans and Workshops that got into cost enhancers but I was able to race and recover against most control decks.
The second version I will call the counterspell version which plays some number of Mental Misstep and Flusterstorm either 4 to 6 depending one what you want to cut. This is similar to what you see on the league list.
It plays more of a tempo game and builds up a number of artifact to PO or just goes for Time Vault lock or a quick Blight Steel if you can protect it (I switched to Steel Wind).
It is OK and has a descent match up but control match ups get very tedious especially when they resolve a Jace or Dack and you have to very careful against BUG.
The third version I will call the discard version I added 2 Duress at first then played around with other spells like Collective Brutality and Thoughtseize. I cut the Mental Misstep and just play 3 Flusterstorm. It has a very good control match but struggles against aggro.
