It's not necessary to use barbarian in the begging and two balloons to destroy center ,you would better take one hog's riders to destroy rocket artillery in the end . Because now attack looks like he cought good luck ,but in the reality dragon may fly diff way ,if skeletons on the left side won't die or sth else.
Yes it is difficult to 1 shot a 11k+ gm as you need precise timings on rams at the beginning to save sparky's health. Below that are not that much hard if you have enough practice.
I saw a similar one, where the player made 99%, because the bombtower destruction blew his last troop. It is possible to 1shot, but it's about absolute precision.
