In this video I talk you through my thought process while doing an Electrone attack at TH10 with the Stone Slammer.
You want your Loons 1 shotting each defence. Below is the minimum number of loons you’ll need so that they 1 shot the respective defence-
Cannon - 3
Inferno - 5
Air Defence - 2
Bomb Tower - 2
Mortar - 2 (preupdate, i need to recheck this)
Tesla - 2
Wiz Tower - 4 (i wrongly said 5 in the video)
Archer Tower- 2
Xbows - 5
Bring at least 1 more than these numbers cos one or more will die on the way
