The thing is by now, I think it needs to be reworked; with 18 video game Types and 11 TCG Types, we can avoid three-in-one Types. Why avoid them? Less deviation in terms of Type relationships:fewer effects meant to apply to Type A1 working on Type B1 (because in the TCG, they are both Type A2) and more accurate Weakness/Resistance. So pre-XY when I did that, I could minimize the deviation by shifting Poison to the Darkness Type. I also found out that it would make more sense now to shift the Rock Type to the Metal Type; not like the names for the original combination Types always made sense. Not sure if it still holds up with the Fairy Type now added.
