A surprising debut match took place earlier tonight on AEW Collision. This comes following a popular former WWE Superstar made a shocking appearance during the show.It is not a rare occurrence for stars from other promotions or the independent circuit to make an appearance for the Tony Khan-led promotion. The company has been open to all forms of competition, including those looking to make a name for themselves.Earlier tonight, an AEW debut took place with Nixon Newell (fka Tegan Nox) and Miranda Alize appearing backstage and challenging TayJay to a tag team match.Moments later, MxM Collection and Johnny TV held their Casting Call Open Challenge, looking for any trio on the roster who wanted screentime and a good fight. To their surprise, it wasn't a trio that came out but CMLL's Olympia, who was also making her AEW debut, and she was set to face Taya Valkyrie. This came as a surprise as Taya did not expect to be in a match tonight.She still pushed through with this, and it ended up being more one-sided than expected. The luchadora was on a mission and completely dominated the match. She didn’t just take down Valkyrie but also went as far as making a top rope dive to the outside to take out the entire faction. This was an impressive debut for the CMLL star and a possible sign of more things to come.Unfortunately for MxM Collection and Johnny TV, their string of bad luck continues as they have yet to win one of their Casting Call open challenges. Even Taya Valkyrie has had a bad streak of her own. It remains to be seen if they'll finally get a breakthrough in AEW.
