>>21523804Niche counters and checks rarely ever work out, and I think Golduck won't work here either.
Even if it does its job and successfully beats Primal Groudon or Mega Rayquaza, what does it do afterwards? If you're running Max HP/DEF and Bold like
>>21523840 describes, its next to worthless in virtually every other situation. It's huge set up bait, it's pathetically weak, it's not worth it.
The biggest problem here is that there are actually competent pokemon that can beat them 1v1. Tanky Yveltal can Toxic and Foul Play both of them to death. Ditto takes them both to task seeing as they're both weak to their own STAB. Hell, you want to get kind of out there, Landorus OHKO's Groudon with Earth Power whilst Timid and Scarfed even, unless its max HP where it 2kos anyway. Passive damage, just launching STAB attacks at them in general since they're not the last word in all-around bulk works.
There's just no reason to use Golduck.
>>21524948Sums it up as well.
