Back from some testing against miracle. I tested some stuff first 4 sylvan library no top but needle ; I have found it to be good game one but after side if both gets hit by wear tear it is game lost. So it is not the way to go
I think.
Second stuff I have tested it is four top main side out the needle ; here both players have access to top ; but miracle does a way better job using top.
So I think the way to go is no card selection (via library/top) and 4 needle in and more artifact targets such as cotv I have retested the mishra's factory plan and it is very good ; it is the way to go against miracle. I now play one mishra main one side. The mishra plan is good if you can answer opponents kills via mentor (decay-bomb) and entreat (ratchet bomb) mishra answers jace and then goes beatdown. Then I have done some little testing with root maze and I don't like the card, it slows down most of the time both player the same way (for my list without accelrations) and it is a dead card late game ; it doesn't affect led.
I have also tested the death and taxes matchups with massacre, but the new sanctum prelate can answers it so I play a split between massacre and not of this world in my side. Here is what I am testing but this list is not settled into stone, it might evolve.
As for people not playing cabal therapy ; it is a wrong way
cabal therapy is clearly
the best discard spell, but for that you have to play
3 probe and 2 khalni garden at least.
Probe is also very good with needle to know what to name and to know if you can go off.
