Spawn your archers around the base or outside buildings to trip off traps and get more percent destroyed. Don't use them all.
Spawn your remaining archers where you will spawn giants. This keeps giant bombs from exploding on your giants.
Spawn giants on where there are nearby defenses (Presumably an open area Air Defense).
Drop your first Heal potion, then your wall breakers on where the giants are smashing to split open the walls.
Drop your second heal potion on where the giants are, and spawn the wizards in the healing area.
After the giants destroy the air defense, use your two healers on where the wizards are. This is how the wizards can keep going on into battle. Two healers can instantly heal archer or cannon shots in a zip.
Wherever a large amount of your Wizards are, you should put down the Rage spell so they can destroy things faster.
(No execution notes)
You could have completely destroyed or almost destroyed a base. Only very very very rarely is an armageddon attack going to make you lose. By the way, this costs around 180,000 Elixr, so you need a lot of loot.
