This week, the worlds of The CW’s The Flash and Arrow will collide in a massive two-part crossover event. Things kick off tomorrow night on The Flash with “Flash vs. Arrow” before wrapping up Wednesday night on Arrow with “The Brave and the Bold.” We know you’re excited. We know you’re going to watch. But what we don’t know is… are you Team Arrow or Team Flash?

We want to know who you’re pulling for, and in exchange we’re offering up four amazing Flash/Arrow prize packages. Each package consists of Arrow: The Complete Second Season on Blu-Ray Combo Pack along with a Flash poster signed by the entire Flash cast—Grant Gustin, Candice Patton, Jesse L. Martin, Carlos Valdes, Danielle Panabaker and Rick Cosnett.

Want one? Of course you do, and here’s how you can enter to win...

1) If you’re not already doing so, follow @DCComics on Twitter.

2) Between now and 11:59 PM on Wednesday, December 3, 2014, tweet whether you’re Team Flash or Team Arrow while using the hashtag #FlashArrowGiveaway. You must use the hashtag for your tweet to be counted as an entry.

That’s all there is to it. After the deadline, we’ll randomly pick two winners from the Team Arrow entries and two winners from the Team Flash ones and contact them via direct message. (So be sure to check your DMs!) Each winner will receive a prize package.

Go on, take a shot at winning. Just be quick, this giveaway will be over in a Flash!
