I would like to propose a move called superior vulnerability impact. All this is, is just superior vulnerability but as an impact.With the release of 2.9 tryko and dio lost a bit of viability with loosing deceleration moves. So I would like to propose that they tryko a resilient impact is replaced with superiority vulnerability impact and for dio it gets superior vulnerability as a base attack and keeps the resilient rampage move.( or superior vulnerability rampage and resilient strike or both). I wanted to give these creatures their current vulnerability from resilient moves but add deceleration to them so they are more like pre 2.9 creatures. This also gives them a bit more of their ankylosaur ancestry.
I really like this idea
I think rhe superiority impact would better suit it
The epic deer has the superiority impact
