I agree with that, Dusclops was trapped by Arena Trap in gen 3 so i think all ghost types should be trapped in gen 2 since levitate doesn't exist.in
I'm a bit confused about the rules in regards to ghost types. The ghost type immunity to trapping (gen 6 onwards) applies to both Shadow Tag and Arena Trap, while you only mention it in regards to Shadow Tag. Additionally, Arena Trap users can trap each other, while you say they do not.
Endless battles only existed in ADV because Shadow Tag could trap other Shadow Tag users. This tournament is using updated rules from Gen 4 and beyond, so endless battles shouldn't be possible here.In
Whydon can we ban leftovers Wobbufett like in ADV to prevent endless battles?
