Find a base with a town hall on the corner. Make sure there are none or very little defenses. If the enemy is in a clan and the clan castle is close to the town hall, you shouldn't attack. Make sure the defenses are not protected.
Drop an archer to test for traps or any hidden teslas.
If there are hidden teslas or the town hall is in range of a defensive building, drop all your giants at it (Unless it is a mortar, and then drop only one giant).
Drop 4-7 archers to get the town hall.
If the enemy has any storage filled at least half way and there is a good amount of loot, then drop your lightning spell on it. It doesn't matter if you don't have a dark elixir storage. You should still lightning spell dark elixir to troll the player.
If the king (level 6 or less) is by the outside of the base, lure it with a few barbarians, then drop all of the barbarians and a few archers to take it out, just to troll.
Drop the rest of the archers to take out any unprotected buildings. Higher percentages give more trophies.
(No execution notes)
There you have it! This is an easy 1 star and should give about 9 trophies. Try to do as many of these as you can, because when the people you attacked get into the game and see the replay of the troll, they'll want to get revenge. If you're not confident that so little troops can succeed, add a few more. You should be OK using this many, however.
