Cosmo Brain is far more likely to be touched than a main box UR like Silver's Cry.

Aaahh... and I thought for a while people didn't know it was a re-work of Cosmo Queen ^^
Can someone tell me why this didn't work: I used controller to sac my creature and gain control of his BEWD. I was unable to sac that to summon Cosmo Brain though. The Blue Eyes is under my control and I should be able to sac it, correct??

Yeah, it didn't seem like there should have been any problem
Just to confirm, genex controer is not consider a normal monster right? So it can't be special summon by Brain but can be used to special summon Brain

Tuners does not affect whether a monster is Effect or Normal.

Easy tips:

Yellow border is normal monster
Orange border is effect monster

Same concept applies to blue purple white etc
For a re-skin of Cosmo queen this card is actually pretty powerful. Rate 10/10

How did you summon them? By the effect of a battlin boxer card? Maybe said effect locks you to on...
You are fired!
You're seriously underestimating it, lol
