Ok. So there are some changes I would implement on your pokemon, mainly being
the EV spread. you seem to just play around with defensive EV's, but the key to bulk on both Def and SDef is investing in HP. Also, you've broke the law of EV's; a EV investment on a certain stat must be divisible by 4, otherwise you're wasting EV's.
Anyways, since Rotom seems a offensive pokemon with 4 direct moves, it would be better if you change his EV spread
into: 4 HP / 252 SAtk / Spd. This way he outspeeds way more pokemon and he is more efficient than with your current spread.
Next is Crawdaunt. His moveset seems very inefficient with his EV spread. It is hard to tell whether your using it as a special wall or not, but looking at the moveset you're using it as an offensive attacker. This is why you should change his spread
into: 4 HP / 252 Atk / 252 Spd. It gives him way more power. Also very important,
you should change his ability to Adaptability. This grants him alot more power for his two STAB moves!
Now, onto Moltres. Protect + Roost doesn't make sense at all in my opinion. I'm sorry if im being rude, but really, in the slot of Protect there could be a way more useful move. His EV spread should be changed into
max Spd max SAtk, those 34 EV's in HP are just a waste of speed and will be a disadvantage for Moltres. If you
really want that 34 EV's in HP, I'd suggest you get those out of SAtk.
Then, Dodrio. This is the disgrace of the team. The idea of a Choice Banded Dodrio is just fine, but really, there is a waaaaayyy more better set than you are running. Also, to a frail pokemon as Dodrio, speed is crucial. This is why he should have
max Spd max Atk. As it is now it gets outsped by a majority of pokemon and he'll get swept really fast.
I will post a summary of changes in the end of this post where I will adress this better set.
Now, Lilligant. Not much to say about it, although Synthesis seems a bit redundant. Since he'll be locked into Petal Dance, it is most likely that he gets swept before you get to Synthesis. In this slot there could be a move for better coverage, such as Hidden Power. Also,
Timid would be the most effective Nature on Lilligant.
Last is Slowking. Again, you're playing around with EV's. It seems that you want to use it as a mixed defensive pokemon, so it'd be better if it was changed
into: 252 HP / 196 Def / 60, with a Calm Nature. Also, Regenerator is the best abillity for Slowking.
Important: Summary of changes.
Dodrio is way more useful now. By using Thrash 2-3 times he will get confused, which
activates his Tangled Feet ability. This way, Dodrio has a higher change to dodge an attack and has more survivability chance. On Moltres you could either run Air Slash or Hurricane, whatever you prefer, Accuracy or Power.
So that was my rate. After you've implemented these changes it will be alot better, but still far from perfect. There really aremore changes that would make it more useful, such as different pokemons / sets. This team has many weaknesses if you ask me. I'll leave those things to another rater :)
Anyways GL with this team and i hope this helped :D!
