first you have to finish brine cave then you have to go to hidden land on lapras . in order to defeat dialga easily you have to be level 50 ( that's important) then bring lots of reviver seeds Oran berries sleep seeds and stun seeds .
when in battle with dialga throw sleep seeds at him before he uses roar of time and you will get knocked out quickly if you don't. then use lots of moves then repeat that process until he is defeated. that's how you defeat dialga.
to get past hidden land and temporal tower just be level 50 like what i said earlier and get to the stairs quickly . oh and before i forget bring things like apples and whatever.

Go to lapras on the beach she will take you to the hidden land beat it and you are ask if you want to continue to temporal tower.
