Need advice few things below:
1. do i Need to continue summon or my monster are good enough?
2. after my Julie(Pirret) 6 star, which monster to up next
3. do i need to swap any monster with the backup?
4. is my atk group good for def? (do i need to make a new def team with the monster above)

sure, will try train water sucusbus after my pierret 6 star

sorry my mistake,
i do not have water sucusbus but got light which is better (33% atk speed)

have trouble to hit 97+100 speed for megan
now have 97+63 only

ops, see wrong

no choice now but use barreta (fire) for 19% atk speed
