>>22579899>they cause the Abilities Drought, Drizzle, Sand Stream and Snow Warning to fail to activate.>If another Pokémon in battle has the Ability Desolate Land or Primordial Sea, the dominant weather condition will be determined by whichever Ability activated last.Delta Stream doesn't nullify anything except basic weathers. Primal weathers are just +1 weathers. +1s can still beat +1s. Delta Stream is just another weather condition.
Actually play ubers sometimes. Kyogre's great. You can revenge kill Primal Groudon all the time with it and it used to be my go-to Rayquaza counter because Primordial Sea overtook Delta Stream and even if Kyogre fainted because Rayquaza was at +2, I could just bring an ice shard user who wouldn't die to +2 Extremespeed and take it out, since Delta Stream only works on switch in.
