For those who wish to enter:

This is the first picture ever made about Steemgar and I personally like the message it conveys on the right panel. Picture tells more than 1000 words so something that explains even a bit about Steemgar would be good for the match announcement posts.

As for avatar, I guess same applies. I'd rather see something related to the game itself rather than gaming in general. But if you have something different in mind, go for it!

So my tip is to try Agar and Steemgar, see what you're working with and go from there. You can check out @steemplayroom for announcement posts. What would catch your eye in the feed?
