It really does seem like that way too much the anime was running on Inverse battle rules. Type advantages just do not work out and type disadvantages seem to work out way too much, and this endured for a significantly long time.

It seems by Gen 7, after the whole Greninja losing to Charizard thing, they cooled down on the nonsensical type matchups, or maybe there just weren't as many memorable moments of that nonsense.

Though in the latest English dubbed Horizons episodes, the Grass type beat a Rock type and the Fire type beat the Grass type. So, they definitely figured it out by this point that not every major battle needs to have disadvantaged type matchups resulting in victory.
