Kingdom Hearts Unchained χ will soon be undergoing maintenance on August 31st. Square Enix have released an update for the August Coliseum to reflect this. They've also released a notice about the new Epic Medal Carnival that brings Illustrated Ventus into the game, as well as Roxas and Namine Avatar boards with Illustrated Aerith!
August Coliseum Update! (Edited 8/25)
Edited on Aug. 25, 2016
Due to the Aug. 31 maintenance, the August Coliseum will now end earlier than anticipated, at 6:00 p.m. (PDT) / 1:00 a.m. (UTC).
We apologize for this inconvenience, and thank you for your understanding.
Calling All Ventus Fans!
"My friends are my power... and I'm theirs!" - Ventus 
Ventus, the swift wind, enters the battlefield!
Illustrated Ventus is an extremely powerful Epic Medal that attacks a single target and lowers their speed-based defense by 1 tier for 1 turn!
Not only that, there’s a small chance of getting an even rarer version that has 1,000 more base strength than the standard Illustrated Ventus! 
* The rare version of the Illustrated Ventus Medal has the boosted strength stat highlighted in yellow, instead of the standard white text.
* The rare version of the Illustrated Ventus Medal can have its Special Attack Bonus strengthened by using the standard version of the Medal as well.
* However, make sure that you don't fuse the rare version onto a normal version, or else you'll lose the stat boost!
We also have Rock Titan, Ice Titan, and Hydra, who are hard-hitters that can fit into your Reversed Medal slots!
And don't forget: You are guaranteed at least one of the above new Medals as well as at least one Epic Medal in your Epic Medal Carnival pull!
