Buying End-Game Summoners War Account

My budget is $300 but I will pay slightly more for accounts with some of the better LD Nat5s (Ragdoll, Yeonhong, Tian Lang, Giana, etc)
Account must be personally owned by the seller for safety reasons
Should be able to complete all in-game content
Higher the better for Arena
Don't care too much for RTA but I'll consider it
Global is preferred
More good nat5s the better
More 6*s the better

Must use an official middleman or go first.
I'll buy the best combo of price / stats
PM me what you have I sold my account a while ago but I feel like playing again
