GABRIEL II vs. Requiem
I actually think I could be okay here - while the HDPE will probably be ripped away if he gets his drum in, I intend on staying away from the drum, and even if he does get a hit in the Hardox and titanium underneath the HDPE will stay where it is. Ill aim to get around and wedge under the sides or back, or get him in a side-by-side waltz which will scoop him onto the front anyway due to Gabriels shape, go to the wall once I have him on the flipper, and try for the OOTA. One more thing - stay well away from the pit if it is opened, and likewise for the dropout zone.

Liar 2 vs. Nitro-Gene 4.0
Nitro-Gene probably has the better chance of winning this because Liar will have to line up its attack more carefully, but it could go either way.

Cyrillium 2 vs. Infusion
Infusion FTW.

E Clawdius Unum vs. Aftershock
Ill go with Clawdius here, it has the control to make Aftershock throw itself in the pit or assist it in doing so.

Good luck Dan
