Dinos that are swap prevented when they swap in can be held an extra turn if you swap out on your next action. This is particularly for quetzo and (if you’ve survived the rampage) DC.
If they aren’t going to fix it, might as well exploit. I know I’ve lost a handful of matches because of my quetzo being held longer than it is supposed to. To the point where I am considering taking it off my team because the typical counter when it swaps in (usually against erlidom) is to switch to tryko right away, which causes the bug, and because of the brainless dodge nerf, even if I get a dodge, I take damage.
This also can explain why you sometimes see DC users go with regenerate, even though the pinned visual is not under them anymore. Even though the pinned circle is gone, the opponent still cannot switch because the button to do so is blocked off.
