I need help for finishing my competitive team

I need two pokemon suggestion to help me finish my compititive team

pokemon on my team:
mega metagross
milotic
tapu koko
landorus t (assault vest)

I feel like i need a bulky and a fire pokemon but any suggestion is good.
Thanks for the help in advance

Heatran would likely be your best bet, yes you would have a huge ground weakness but it is among the bulkier fire types. you could add a flying type as your last mon to lower this weakness. I do wish to ask is this VGC or some alternative format?

It's for vgc

Heatran is a pretty solid Pok?mon to run, your team has a big ground weakness however so it's maybe not the best idea.
I would recommend running both Clefable and Zapdos

Zapdos @ Rocky Helmet
Ability: Pressure
EVs: 248 HP / 240 Def / 20 Spe
Bold Nature
IVs: 0 Atk
- Discharge
- Heat Wave
- Defog
- Roost

Clefable @ Leftovers
Ability: Magic Guard
EVs: 252 HP / 4 SpA / 252 SpD
Calm Nature
IVs: 0 Atk
- Fire Blast
- Moonblast
- Wish
- Toxic

Depending whether you run Landorus as a Special Attacker or not, I would probably swap out Clefable for a Tapu-Lele.
You could run something like this:

Tapu Lele @ Choice Scarf
Ability: Psychic Surge
EVs: 252 HP / 4 SpA / 252 Spe
Modest Nature
IVs: 0 Atk
- Moonblast
- Hidden Power [Fire]
- Psyshock
- Shadow Ball
