I’m making a team, how does it look?
Eevee (Mega)
Delta Garevoir
Delta Volcarona
Delta Haxorous
Delta Bisharp
(Don’t know yet)
Eevee (Mega)- moves should be ones that cover the other team members, like Ice Beam specifically to deal with ground weaknesses, while it’s true you have a water & an ice type both on your team, but unlike Eevee, they form a double-edged blade, it you use them on ground types, they have a 50-50 chance being taken out by said ground type, meanwhile, you could also teach Psychic or Psyshock to deal psychic-type damage, which, like D. Bisharp, deals away with fighting types, while also dealing with Poison as well, Moon blast or Dazzling Gleam to deal with your Eevee’s type disadvantages & giving way for beating down dark type, Espeon’s weakness. The last move is your choice, but the moves given won’t deal with Ghost(Shadow Ball/Foul Play/Pursuit), Fire(Hydro Pump/Scald), Rock(Hydro Pump/Scald/Leaf Blade), & Steel(Flare Blitz/Fire Blast). But this is my opinion, I’m just giving a fair idea.
Delta Gardevoir- Moonblast deals with fighting type Pokémon, being one of the strong fairy type moves. Thunderbolt & Ice Beam both deal certain aspects, having 100% accuracy compared to their stronger counterparts(Thunder & Blizzard), Ice Beam covers against ground types, while electric & Ice together covers against the flying type Pokémon, as well as giving STAB(Same Type Attack Bonus) boost, & finally Earth Power, because of it being the type Gardevoir needs to combat it’s last two weaknesses, Fire & Rock, fighting being covered by Moonblast, & Ice Beam covering Ground Types. If you don’t want Thunderbolt, Volt Switch is available, allowing you to switch out at a moment’s notice.
Delta Volcarona- unlike the others, I recommend Levitate, it gives Volcarona(outside of miracle eye & irrelephant) the immunity to the ground type weakness(aside from ability breakers, like Mold Breaker & Gastro Acid), to combat ground type, teach either Giga Drain or Energy Ball, for recovery, Roost or Moonlight, depending on which ability, but I recommend Roost cause it’s not dependent on weather like it’s light based counterpart. Handle Psychic types with Dark Pulse, a chance of flinching, as well as STAB & 100% accuracy. Hyperspace Hole because it also by passes all forms of protect(i.e. Detect, Spiky Shield, & Kong’s Shield for example), I also recommend the armor for D. Volcarona, it boosts defenses by 33%.
Delta Haxorous- Have the Heavy Metal ability, Heavy Slam, Heavy slams does double what it would do, because Heavy Metal doubles weight of the Pokémon, Aqua Tail deals 90 damage, as well as STAB & deals with ground types, Draco Jet, barely any types outside of steel & fairy types, can resist it, priority move. For the last move is Earthquake, in double battles, levitate on Volcarona is useful for this move, you could also give the Assault vest, this allows Haxorus to gain greater Sp. Def.
Delta Bisharp- Defiant, stat lowering moves or abilities sharply rises Attack(2 stages in other words). Drain Punch giving STAB & recovers health. Stone Edge, critical hit boost, deals with flying moves. Fling with King’s Rock, & Acrobatics.
I can say my opinion, but Bisharp was difficult to figure, you don’t have to take my advise, but this is recommended in my words, so see if they work. If I were to give Pokémon as your final member, it be Delta Metagross(spider).
D. Metagross’s typing is unique, being covered thanks to your other team members, give them the Poison Heal ability, either Toxic Orb as a held item, give them Stealth Rock, deal great damage to all types, depending on them, this takes chunks out of Fire, Ice, Bug, & Flying types. You could maybe have access to Toxic Spikes & maybe Sticky Web, but if not, you could have X-Scissor it deals with Bisharp’s Psychic weakness, Earthquake deals with Steel, Rock, Electric, Poison, & Fire. While the last move may be a gamble on my part of possibility, Knock Off literally knocks an item off someone, deals more damage if target possesses an item, but aside that, the type balances & helps deal with ally weaknesses, &/or Be a good entry hazard Pokémon.
