[Game Mode Concept] Enter the Void
Map: This could take place on a void-themed skin for the Howling Abyss.
Goal: Defeat the other team and cross the gates into the Void portal (instead of Nexus).
Champion Pool: Similar to Blood Moon's assassin lineup, this mode would only feature the 7 void champions -- Kog, Malz, Kha, Cho, Kass, Rek, and Vel
Gameplay: The gimmick for this mode would be that it will stay fresh despite the small champ pool, as the basic abilities will shuffle each time you use one of your spells, with the exception of your passive and ultimate.
So if you pick Malzahar, you will start the game with your normal kit, but say you use E - Malefic Visions as your first spell on an enemy minion wave. Upon coming off cooldown, your E will now be randomly replaced with one of the other 7 E's available throughout all the Void champions (yes, I said 7, so there's a chance you could get your own E back again). You could potentially end up with two silences if you get a Chogath W and still have your own Q available.
The reason this would take place on the Abyss would be to emphasize the randomness aspect of the game mode, as it would just be a chaotic spell-slinger.
What do you guys think? I think it could be pretty fun. Comments, ideas? Perhaps ultimates could be switched out too, but that seemed TOO chaotic to me lol
