Is this real life or is this just fantasy?

I'm happy to report that this time around it's both. Sorta. MMAmania.com is happy to introduce the first-ever "fantasy" mixed martial arts (MMA) tournament that will use "real" collectibles from Round 5's latest series.

Officially hitting store shelves today Sept. 12, 2012 (Walmart in Canada, Toys r Us in the US), the Ultimate Collector Series 10 features 12 new figures, including the miniature debut of Ultimate Fighting Championship (UFC) Bantamweight Champion Dominick Cruz.

In addition, perennial middleweight contender Chael Sonnen, heavyweight striking sensation Alistair Overeem, former World Extreme Cagefighting (WEC) Lightweight Champion Anthony Pettis, and the first man to claim the UFC heavyweight championship belt, Mark Coleman, are also part of the latest Round 5 line up.

That's not all.

Ultimate Collector Series 10 also boasts new figures for UFC Middleweight Champion Anderson Silva and former UFC Light Heavyweight Champion Lyoto Machida.

All these great fighters crammed into one small package makes me think only one thing: If a fight erupted at some point in the shipping process, which fighter would emerge from the box the lone victor?

That's where you come in.

MMAmania.com and Round 5 are going to stage an Ultimate Collector Series 10 fantasy tournament. We'll set the brackets. You'll choose the winners of each fight with your comments and votes. Then, when we have the Ultimate Collector Series 10 field whittled down to two fighters who you select, we'll look to you to tell us who wins and all the reasons to support the prediction.

The three readers who provide the best predictions for the final fight will win a factory sealed case of Round 5's Ultimate Collector Series 10 (Regular Edition).

We'll post the full bracket and first round fight later today. Stay tuned. In the meantime, feel free to find out more about Ultimate Collector Series 10 and Round 5's products right here.
