TH snipe using BArch and pack a couple lightnings to get rid of a mortar if the TH is only protected by one mortar.
If all 4 teslas pop up, I try to send some barbs and archers directly at the teslas on one side before resuming TH onslaught. If only a couple teslas I will often just deploy enough troops to overwhelm the tesla fire and keep the troops aimed at hitting the TH directly.
Obviously you want to check for traps so I usually scatter a few barbs and/or archers first.
Upgrade your army camps first since this gives you more space to put more troops when attacking. I upgrade archers first, then barbs, currently doing minions and then will prob upgrade drags to get rid of some excess elixir but have to wait several days for minnies.
Just worry about offense if you are pushing. Keep at least a couple hundred thou gold for nexting just in case things go badly dry.
I personally set my DE storage out next to my TH in Crystal to hope for a one star shield. Costs them nothing if they use a hero and only a few troops if they use troops.
Check mines/collectors to see if they may have a good amount of gold. I don't worry much about elix, it seems to be something I don't run low on so have no problem throwing a bunch of archers at a mine to get 500 gold or whatever and completely skip elix unless it is out of reach of all defenses.
Have sessions of a couple hours if you can and spread out the distance between sessions to use the shields getting other stuff in life done. When getting close to log off time, I will often use my lightnings on anything with gold just to get rid of them knowing I will be offline for awhile and can queue up 3 new ones. I gladly waste elix to get more gold.
If heroes get involved make sure you stop deploying troops and lure them away to get them. Also be careful not to have the AQ firing behind a wall while your archers fire into the wall after AQ attacks because AQ has more range.
Good luck! You'll be in Crystal soon if you are patient and consistent.
