"RNG"

We_are_Venom

So lately I've noticed I've been pulling covers in batches. It started about 3 weeks ago with Falcon where with back to back standard tokens I pulled 2 of his purple which I already have 5 of. His DDQ hit netting me his 5th yellow, and that same day I pulled 2 more yellow from heroic tokens within minutes of each other.
After this it was classic Magneto, which I pulled 3 blue, which I had to sell since I had 5 and he's only got 10 covers.
Then it was 3* Daken purple and I pulled 3 of those. I already have 5.
Storm green I pulled 3, already had 5.
Daken 2* I pulled 7(!) Black within 2 hours.
Wolverine yellow 5, same day.
I pulled 5 2* cap blue the same day going 0 to 5, and pulled 3 more a day later.
I got 2* Bullseye from 94 to 103 pulling only purple over the course of a day and a half.
Today, I've pulled 6 2* marvel covers, 5 being yellow, which I already had 5 of.

This doesn't strike me as random. It feels like RNG is broken.

Roughly two weeks ago I sold 13 4* characters. 15 LT/CT later, I have every single one of them back with the only new cover being bss. It seems IMPOSSIBLE that I would consecutively pull every MF character i sold, but it happened.
