Solrock

The shift to the DPP metagame was rather unkind to Solrock. While Solrock had some uses in OU during the glory days of RSE, it's lucky to find any use in NU today. It has a unique typing and a great ability, but its plethora of weaknesses to the most commonly used attacking types and below average defenses mean that it'll usually be KOed before accomplishing much on the battlefield. That may seem like a lot of bad news, but this shouldn't deter anyone from choosing Solrock, as it has access to a myriad of supporting and attacking moves, as well as a unique typing and ability that can offer useful resistances to fill specific niches in your team.
