Top 1k ladder finish in clash royale

I used KingBoost for Clash Royale and honestly the results were crazy. My booster (@kareto7932) took my account from around 1600 medals all the way up to top 500 (peaked around 2800+). The gameplay was on a completely different level which is very consistent, almost no mistakes, and he was able to win even with a non-meta deck. He promised me to get the top 1k finish in ladder and did it which is remarkable. On some websites booster fell short on reaching top 1k because it's end of season and many top players are pushing to their best but this guy @kareto7932 is beyond any top ladder player. There were moments where he struggled a bit at higher ranks (which is normal), but overall he handled the climb really well and even recovered from drops. I would recommend him to anyone that wants a top ladder finish.

Customer support was decent, they responded and got things moving. No major issues there. Overall great service and I would definitely come back for more.
