Deploy your Grand Warden on one side to clear it, pick a side which you can get much value, like an multi-target inferno tower. Deploy 2 balloons to check for seeking air mines, then deploy your healers on your grand warden.
As this process is going, deploy your siege barracks on the other side of the base to clear it. also use your jump spell on the middle. With all sides gone, the main army will be pushed to the middle.
Once the Grand Warden have gotten the value you want, deploy your yetis to the warden's aura to draw him away. deploy a ice golem to tank then deploy your bowlers behind, following by the king and queen. deploy remaining balloons.
Use rage spell to help your army get through, and then use your earthquake spells to open up compartments.
If there is clan castle troops, use poison spell to slow them down.
Once the army get to the middle, rage them and use the grand warden ability to protect. Deploy your Royal Champion on a side to force the army through. Use remaining spells to clean up.
