Magmortar

Magmortar is a fantastic wallbreaker often capable of single-handedly dismantling defensive teams thanks to its great coverage options, its high Special Attack stat, and Taunt. Although Magmortar usually takes advantage of Z-Crystals to lure in and KO Pokemon like Audino and Vaporeon, it can choose to utilize Choice Specs to 2HKO virtually every one of its switch-ins. Magmortar also possesses decent special bulk, which lets it act as a soft check to threatening special attackers like Sceptile, Comfey, and Whimsicott. Unfortunately, Magmortar's poor physical bulk and weakness to entry hazards limit its ability to switch in repeatedly and leave it easily revenge killed by faster attackers like Aerodactyl, Choice Scarf Passimian, and Mega Glalie. Additionally, although Magmortar's Speed is fine for matchups against defensive teams, it gives Magmortar a lacking matchup against offensive ones, giving it fewer opportunities to safely wallbreak.
