I want to reserve
Delcatty. Many would say why i would choose Delcatty, which the answer is very simple. While Delcatty isn't one of the most threatening Pokemon on the metagame -- it has quite a useful niche. In NU, one single member such as Feraligatr with boost properties can end your chances from winning. Delcatty actually helped me survive the battle and ultimately win. This is one good Pokemon with good priority moves, and if you dont have one, i suggest you try it. Which is why i want to make an analysis for this Pokemon.

My second Pokemn that i want to reserve is
Cryogonal. At first, I thought that i wouldn't use Cryogonal. But i wanted to deal with Stealth Rock users, so i searched for a fast spinner, and here he is Cryogonal! If someone wants a good spinner i highly recommend Cryogonal. The benefit of using a Cryogonal is predicting your opponent. The drawback of Cryogonal is using him in the wrong time or against a strong Pokemon that can overwhelm it -- either super effective moves or anything that can land a crit that can KO it. But Cryogonal is useful for situations that might arise, especially if you're facing a water-type. You can use Freeze-Dry to gain the upper hand, and you can also deal with flying-types such as Archeops with Ice Shard + Freeze-Dry (a favorite NU) pokemon. This pokemon deserves more appearances and an analysis.
