-Happy Semiconductor - Good choice. This should always be used in every tourney.
-Bad Bunny's Lair - Don't you mean BloodBunny's Lair? Or this a new level?
-Jungle's Edge - Yep, very fast paced and nice base placement.
-Medieval Skyscrapers - Yeah, its a great level.
-Diamondus Warzone - Nah, I've personally never liked this level. There's too many random platforms. And I find it boring, there isn't really any special about it.
-Security Breach v 2.0 - Yeah, keep this in.
-Atom Heart 234.5 - This level is a bit slow placed and a bit cramped. But it's still fun too play in, so I guess that's the most important thing.
-Quasar Quandary - No mappool would be complete without this.
-Space Island Level With Islands - Interesting choice, I haven't seen this used in a mappool before.
-All Your Base - Another awesome level.
-Russian Satellite - I don't really like this level much. This one is probably only in because it's your own ;p
-Atmospherical - Darksonic's latest release is a good choice for this tourney.
-Charnel Keep - Yay my favourite level!!!
-Radiation - This level from New Ages is a good level, but it's not so good with team games since it's quite small.
-Zaitox Station 67 - What kind of mappool would not have this classic?
