I just did this, I was worried that I have played too much that I wouldn't get all the packs but it gave me about 19 packs for these. You need a 300 sr investment to make all of them but at worst if you get nothing, you can dust the ones you made for 100 sr so it really only costs 200. I got 3 ur cards that I got rid of and a Typhon. Overall, I got lucky but it only cost me like 60 sr because I pulled a couple sr cards. Some packs get you other packs. Keep in mind all of the free pulls are the first time you see the pack so you are taking rewards that you would get naturally later but for me it very much worth it, thanks!

Finally, an easy method to obtain CP.

Thank you lad, got really nice pulls and UR's

THANKS A LOT!!!

damn!! is there more like this or is this the only cards to do with?

Trick only works once per account XD

free UR what now

some cards are way too overpowered and still have no limit condition... and also this game rly needs some kinds of taunt/chat during duels... it feel so dry without any kind of interaction between duelers

It looks like once you have 27 secret packs you have to let them clear over time, also any sr cards that have more than one source on how to obtain works with this.

Sadly this doesn't work anymore.
