>>43903876I don't see any clarification as to if it is special or physical, so I'll operate it on being either one.
>BlastoiseDoesn't really fit on any common set, maybe the rare defensive spinners. Not particularly useful.
>GolduckGolduck isn't good, but perhaps will see some usage in lower tiers. Momentum is always a nice to have.
>KingdraUseful if special, less so if not special. Reduced to purely momentum utility if not special.
>StarmieUseful if special, less so if not special. Reduced to purely momentum utility if not special.
>Vaporeon4 move slot syndrome. Having it would be nice, but it means taking something else away. Vaporeons already are in want of Scald, Wish, Protect, Toxic, Haze, and Heal Bell. Not likely to see much use.
>MewIt already has U-Turn and Volt Switch, and essentially never uses either. Not useful.
>SharpedoUseful. Sort of like U-Turn on Ninjask. Less useful if it isn't physical.
>MiloticSee Vaporeon. Same issue with 4 move slot syndrome.
>BasculinUsefu, less so if it isn't physical. Reduced to purely momentum utility if not physical.
>KeldeoUseful, less so if it isn't special. However, considering Keldeo can force a switchs much more easily than others on this list it may simply have utility in pure momentum plays. A given on Scarf Keldeo sets.
>DragalgeIn the rare cases where momentum is needed under trick room I guess? Dragalge forces switches given how powerful Specs is, so it may be run purely for momentum.
>ClawitzerSee Dragalge.
>PrimarinaSee Dragalge.
>WishiwashiSee Dragalge.
>BarraskewdaSee Sharpedo.
