Rotom-A is a very unique Pokemon in that it gains an extra move by changing its forme, said move being Leaf Storm for Rotom-C, Blizzard for Rotom-F, Air Slash for Rotom-S, Overheat for Rotom-H, and Hydro Pump for Rotom-W. Rotom-W and Rotom-H are the most common forms by far due to their much superior coverage moves. When combined with its STAB Thunderbolt and Shadow Ball, along with its respectable Special Attack stat, it can succeed immensely as an offensive Pokemon. Rotom-A is most commonly seen utilizing a Choice item (Specs or Scarf) with both of its STABs and a coverage move, rounding the moveset out with Trick to cripple walls by giving them a Choice item. Will-O-Wisp may also make an appearance, allowing Rotom-A to cripple physical attackers. Hidden Power Ice can also be used for coverage against Dragon-types and Grass-types if using Rotom-W or Rotom-C. Rotom-A has access to Pain Split, which in combination with Substitute and its low HP stat allow it to recover its health from a lower amount. Rotom-A learns Charge Beam, which can be used as a boosting move to sweep teams. It even has access to two weather-inducing moves, one being Rain Dance, which can be setup to boost Rotom-W's Hydro Pumps. Rotom-W and Rotom-H are the two most common formes and the two to look out for, as they got the better end of the stick when it comes to the move that they received. To top all of this off, it has Ground-, Normal-, and Fighting-type immunities along with a myriad of resistances to grant it many switch-in opportunities.
