Yeah it's difficult to get a Silver in Normal Gacha for sure
It's a habit of mine to try it nonetheless.
I call it: Moarsi's Hoodoo Voodoo
Don't know if you guys remember him.
He was infamous for getting Rainbows left and right on Nutaku.
Myrdin knows him as well.
He always wrote a n1 story about Moarsi Gacha Demon
