Hello everyone, this is my second RMT in ORAS ou. This team is built around mega diancie.
Crystalium (Diancie) @ Diancite
Ability: Clear Body
EVs: 8 Atk / 248 SpA / 252 Spe
Naive Nature
- Protect
- Moonblast
- Diamond Storm
- Earth Power
This is the standard mega diancie set. Protect is mandatory because diancie's pre mega speed is so low and it loses its defenses when it mega evolves. I usually lead with this pokemon to secure the mega evolution. Moonblast and diamond storm are the 2 stab moves while earth power is for coverage against poison and steel types. Max speed investment with naive nature makes mega diancie as fast as possible. The 8 attack evs are to guarntee the OHKO on zardx with diamond storm. The rest is put into special attack to power up moonblast and earth power.
Tyrant (Tyranitar) (M) @ Choice Band
Ability: Sand Stream
EVs: 180 HP / 252 Atk / 76 Spe
Adamant Nature
- Stone Edge
- Crunch
- Pursuit
- Earthquake
This is second part of my rock spam core. Mega diancie and banded ttar wear down bulky ground and steel types for each other, while also providing some type synergy. Ttar can also trap psychic and ghost types with pursuit. I decided to go with a bulkier ev spread, putting only 76 evs in speed to outspeed uninvested base 70s. Max attack with adamant nature makes me hit as hard as possible. The rest is put into hp to make ttar very bulky.
Spagetti (Tangrowth) (F) @ Rocky Helmet
Ability: Regenerator
EVs: 252 HP / 252 Def / 4 SpD
Relaxed Nature
- Sleep Powder
- Giga Drain
- Knock Off
- Leech Seed
My team currently has 2 ground weaknesses, so a sturdy ground resist is a great asset to my team. Tangrowth can switch in to any ground type consistently. With regenerator, I can constantly use it as a pivot. Sleep powder cripples an opposing pokemon, while leech seed can sap health to make tangrowth live longer. Giga drain provides a reliable stab and knock off removes items. I chose a max physical defense spread to live more physical hits, espically earthquakes. I chose rocky helmet for its item to discourage physical attacks.
Hydropony (Keldeo) @ Choice Specs
Ability: Justified
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
IVs: 0 Atk
- Hydro Pump
- Secret Sword
- Scald
- Icy Wind
Currently, my team struggles against steel types, especially bisharp, so keldeo is a great choice to check them. Ttar complements keldeo very well by removing psychic and ghost types. I choice the specs set because I need more wallbreaking power. Hydro pump and secret sword are powerful stab moves, scald for a reliable water move and a chance to burn, and icy wind to slow down enemies as well as hit grass types.
Pompeii (Heatran) (M) @ Leftovers
Ability: Flash Fire
EVs: 252 HP / 12 SpA / 244 Spe
Timid Nature
IVs: 0 Atk
- Lava Plume
- Stealth Rock
- Taunt
- Toxic
I need a stealth rocker, so heatran is a great choice because it greats an fire/water/grass core as well as provides another steel type check. With a timid nature and 244 speed evs, it can outspeed adamant excadrill, which troubles my team. Lava plume is a good fire stab which can burn. Stealth rock provides chip damage, and taunt and toxic provides a stallbreaking combination. 252 hp evs make it tankier, while 12 special attack evs make it do a bit more damage.
Fairly (Clefable) (F) @ Leftovers
Ability: Magic Guard
EVs: 252 HP / 172 Def / 84 SpD
Calm Nature
IVs: 0 Atk
- Calm Mind
- Moonblast
- Soft-Boiled
- Thunder Wave
Lastly, I needed a win condition as well as a fighting check, and clefable is perfect for this. With magic guard, calm mind, and softboiled, it can setup on many attackers and eventually do a lot of damage with moonblast. Thunder wave helps it set up on faster attackers as well as crippling them. The ev spread and nature is the standard spread. Leftovers allows it to be less reliant on softboiled.
Threats:
Ground types: Tangrowth is my only ground resist and if it gets taken down, my team is nearly done.
Hazard stack teams: As my team is grounded and I have no hazard removal, I get worn down fast with spikes.
Please provide feedback for my team and tips to improve it.
