The deck has no bad matchups I can see so far, although against combo an early sphere of resistance or trinisphere is necessary.
I dont believe you. I dont see how you should be able to have a good match-up against:
Tps: You dont have anything maindeck that should present any problem consistantly. Even the old and vey powerful 5/3 had problems in this match-up even though it had 4 3sphere.
Oath: how are you going to slow them enough down to be able to kill them before they kill you? I know that crucible/waste can be powerful, but if they resolve an Oath I bet you'll be in great trouble.
Food chain goblins: how will you stop them form overrunning if you dont happen to have a sphere on the board. Game 2 it gets even worse with sb cards like artifact mutation.
Control slaver/SSB: How do you deal with a welder? You dont run trisk in main. The only thing to get rid of it is duplicant.
If I'm wrong please tell me why.
