Sp.Atk.: 336
Speed : 150

NPC Advantages: no requirements. gardevoir (life dew, synchronize), burners (drifblim, arcanine) and intimidators (staraptor, arcanine, tauros) help.

Strategy: harden, 2x earth power, after your stats reset 2x harden, rest if HP gets low, earth power, terastalize, harden, 4x calm mind, if you aren't done buffing but need HP attack with earth power, 2x calm mind, earth power until shield is about to break or just broke, optional attack cheer, earth power to victory. if you get burned and you're already healing with the shell bell, don't bother using a heal cheer.

Notes: ‪@newestuser75‬ correctly pointed out that moonlight is a better option than rest, since it doesn't put you to sleep.

Pros: supereffective tera type matching base type, excellent HP, def, and spatk stats. outspeeds emboar. resists head smash, immune to wild charge, harden buffs 1 def stage, rest heals full HP bar. shell bell heals when attacking, proportional to damage dealt, and recovers HP lost from burn chip damage. earth power has a 90 base power, 100 accuracy, and it deals supereffective STAB (tera-boosted when terastalized) damage. it also has a 10% chance of lower spdef 1 stage.

Cons: weak to drain punch before terastalizing. can only buff 1 def stage per turn, can only buff one spatk stage per turn, has to buff its defenses and offenses separately.

Overall Rating: 8/10
