For those players who say you will get banned after using this hacks, you are doing it wrong. I've been using this for the past 3 events and my account is still alive. Dont be greedy on exp and your account will be fine. I suggest you play on your regular phase. Just use the hack to save some repair times and to waves that you cant beat. Dont overdo it, dont rush your exp gain. Do not aim for the leaderboards if you use this hack (unless you coin too).
