So, you did use Red-Eyes Fusion and then "for some reason" you cannot summon any other cards anymore? That's crazy. I wonder if Red-Eyes Fusion has some "hidden" mechanic going on.

Read Red-Eyes Fusion carefully. Find a mirror. Give a facepalm.

Nope. Been using Cosmo Brain for 6 months now and not happened to me once, as long as it's possible to use it.

Kozaburo, Kaiba's father, used Cosmo Queen in anime. In that case, there is a strong relation of Cosmo Brain with Kaiba.

Do we have an R dream ticket too ? I want another one of these

There's no rare dream ticket as far as I know. There might be one in the future, though, considering how popular certain cards like this, AG Wyvern, and AG Frame can be since a lot of people don't like paying for exclusive cards

There won't be any because it would lower their profits.

Why would a company spend resources on a feature that will lower sales?

It's all about money.

Yup. Most guy I fought drawn this card together with Blue Eyes White Dragon on the first turn. By throwing Blue Eyes to the graveyard, this card come out on the field with unsurpassed ATK.

Is buying the the blue eyes deck the only way to get the card cosmo brain or are there other packs/events that allow you to get multiple copies of the card?

And even further, you can go to your local card shop where you can get good insight from experienced players and sellers.

Wait how does it work with duel links? How do they manage to give us the card like that?

Yeah, that doesn't work

I think everyone misunderstood. No, you can only get one copy in duel links, unless you pay real money to get another of the decks.

I cant use his ability in the first turn I have him. That just ruins the flow and opens the game for the other player

It sais is needs to discard 1 Non-effect monster to the graveyard to summon, my opponent sends Dragon Spirit of White to the graveyard (which is a effect monster) and summons it? Is it supposed to work like that?

Yes, Dragon Spirit of White is treated as a Normal Monster while in the hand and Graveyard.
