I use MoS a lot vs sub and it's working out pretty well. It can be very hard for sub to get in if you're aggressive with the orbs. If sub tries slide punishing your second othe he gets caught or it trades and still gets caught allowing you to followup. Even if he freeze punishes you for throwing a second he can't follow up, you're thawed before he can get in. If you use a beam on his wakeup he can ex slide and you get hit but he gets stuck and you can follow up for more damage than his slide did.
I use a backwards orb for my first one and forward orb for the second. Forward orbs look similar to his projectile so they are more likely to punish. If he doesnt get caught in the beam you have time to throw a projectile and another orb before the beam runs out.
It's still not an easy match, at least for me, and even though TG is my strongest style, I have a much easier time with MoS.
