I am fairly new to Pokémon competitive battle and I want to start because I don't have else to do in Pokémon Shield. I think I have a fairly good team for singles but the last 2 Pokémon I don't know what to do with.
Here is my team currently:
Excadrill
Ability: Mold Breaker
Holding: ???
Jolly, 252 Atk 252 Spe
Earthquake, Iron Head, Swords Dance, Rock Slide
Lapras
Ability: Water Absorb
Holding Choice Specs
Modest, 252 SpA 252 Spe
Freeze-Dry, Hydro Pump, Ice Beam, Hyper Beam
Hydreigon
Ability: Levitate
Holding: Life Orb
Timid, 252 SpA 252 Spe
Draco Meteor, Nasty Plot, Roost, Dark Pulse
Hatterene
Ability: Magic Bounce
Holding: ???
Bold, 252 HP 204 Def 52 SpD
Calm Mind, Psyshock, Draining Kiss, Mystical Fire
Moltres
Ability: Flame Body
Holding: Heavy Duty Boots
Adamant, 252 Atk, 252 Spe
Defog, Flare Blitz, Roost, Brave Bird
Tsareena
Ability: Queenly Majesty
Holding: ???
Adamant, 252 Atk 252 Spe
Power Whip, Knock-Off, U-Turn, High Jump Kick
With that, I feel like Moltres and Tsareena are the weak links and don't contribute much to the battle; what could I replace them with? Also please suggest items for my Pokémon to hold with "???"
