I have mixed feelings about this Pokemon.
Typing: Water and Steel is GREAT! It gets resistances to Normal, Flying, Steel, Water, Rock, Psychic, Bug, Ice, Dragon, Fairy, and an immunity to Poison. Its only three weaknesses are to ground, fighting, and electric.
Ability: Just average in my opinion. More people tend to use Mega Launcher, which could be used, but even with Mega Launcher and Water Pulse the base power is just as much as Surf. It does get good coverage in Dark Pulse and Aura Sphere, but I’m not sure if its the best ability. I personally like running Filter more because of its consistency.
Stats: D. Magmortar has good attack stats with 95 atk and 125 special attack. It also has 83 speed which means it could be used with a choice scarf. However, the biggest weakness on this thing is its defense. 67 Defense is extremely weak and allows it to be destroyed by most Physical Attackers that have a neutral/effective move.
Moveset: This Pokemon has a great moveset! It gets Aura Sphere and Dark Pulse (which can be paired with Mega Launcher), as well as Ice Beam, Thunderbolt, Flamethrower/Fire Blast, Shadow Ball, and Energy Ball. It also has decent STAB moves in Flash Cannon and Water Pulse / Surf.
Here are some set ideas that I have:
- Choice Scarf Set
Delta Magmortar @ Choice Scarf
Ability: Mega Launcher
EVs: 252 SpA / 252 Spe / 4 Def
- Water Pulse
- Flash Cannon
- Aura Sphere
- Dark Pulse
Pretty basic set, basically gets STAB for every move with Mega Launcher.
- Assault Vest Set
This set is super risky. Since D. Magmortar’s defense is super low, this is a set you can switch when going against a Special Attacker.
Delta Magmortar @ Assault Vest
EVs: 252 SpA / 252 SpD / 4 Spe
- Flash Cannon
- Fire Blast / Flamethrower
You can also use Superpower as you will only use this set to fight Special Attackers.
Let me know what you guys think, not sure about my opinion on this analysis.
