Yeah they are op and I have maxed regular foils common rare epics and lvls 3 legendaries.

But I play in gf fray 20 in tier 5, which is silver league and because of that I opened enough packs to have all commons rare almost epics and some legendary in gold foils only for silver league.

I decided to not open more I miss maybe few cards or bcx and still I have 1.3M merits. 🥹
