"This card gains ATK equal to the Level of the monster sent to the GY this way x 200"

Yep, the level in the GY counts. The level it had on the field doesn't matter at all.

The text which reigns supreme says it's 200x the card that "send to GY" not the card that is "in the GY".

Here's what happens in order:

1) You summon Cosmo by its own effect by sending a monster to the GY.

2) Cosmo's 2nd effect activates. It checks the monster's levels that is now in the GY. In this step, you don't care anymore what level it had in step 1) because this step is a different effect.

FYI: That's also the reason why you can use Embodiment of Apophis for 1) but you don't gain ATK because in 2) it is a trap and not a monster. That is the official ruling of this card:

A trick up their sleeves... you sound like someone who got their butt handed to them a lot. It's because of baby players like you that konami had to limit everyone else lol.

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
