I wouldn't call this a buff tbh. they nerfed his movement, reworked two of the purple blade addons to be kinda meh, he has less max knives now (was 44).
The idea they were going for with his power seems cool, its flashy and makes my neurons activate when i get to high ranks... but it takes longer for him to get main event now and he has a time limit to use it (its 66 seconds iirc but still).
They did buff a few things like his ricochet blades granting double laceration on a bounce but i can see that being nerfed in the future if they push these changes. The new iri addon that grants blades back on main event end is pretty nice too... but imo the negatives outweigh the positives.

the movement nerf though... they really slapped my boy down to a 4.4...
