1. Golduck’s ability would not work with his moves by current Pokémon definitionsBut Envision Waves doesn’t do any damage, it’s a pure status move with no base power (like a weaker Geomancy). It also doesn’t boost until the end of the turn, so the +2 Stats including SpD won’t help it, even if the opponent is slower than Golduck. Think of Wish, you cast a wish but it doesn’t heal until the end of the turn, so if the foe finishes you off before then you cannot benefit.
This is crucial because it allows say Kyogre with no Speed investment to use Thunder on Golduck on the same turn Golduck boosts, and Golduck is literally a sitting duck since the boosts occur at the end of the turn, even if it outspeeds Thunder when it casts the boosts.
Also Fragmented - why is Unown encouraged to use a STAB Psychic move at 168 base power off of 145 Base Attack, but Golduck cannot use a 160 base power Psychic move off of 100 SpA?
Golduck won’t have the same Speed Tier, and Unown can even use Quiver Dance to further boost even Speed.
I just wanted to confirm.
2. Unown’s high BP is only for one move and golduck has ridiculously good coverage for every typing, sacrificing “what makes sense” (for lack of a better term) for the sake of synergy with the ability. The abundance of out of place base power moves ie blast burn is what shivers my timbers.
Envision is fine tho
