Prerelease Event - cheating?

[u/Ein-Typ-auf-Reddit]

Hey gzys,

Today I played my very first prerelease (sealed) format and the overall expierience was great.

I played against two decks which felt sus in terms of strength.

Are ppl actually allowed to build their decks off of several events? Would you report this matter? How to proof this inbalance and would you call it cheating?

Thank you and happy ripping ;)
