I was thinking that pvp needs more than Blast and Lockdown..So i thought why not use shields in pvp game?
The idea is to play free for all or teams of 2!Imagine a stage where the players bump each other to send them out of the stage..

==The Mechanism==
The player will use his shield to press bump..If the opponent is off guard and wont press the opposite direction button arrow,then he wil slide and eventually drop..
I think a good idea is to keep the dash move..It ll be funny to evade someone who wants to push you..if you try to bump air space you will slide
The player/team with the less drops will win the match

==About gear==
Gear doesnt matter..it ll be pure skills(and connection lol) like blast

==Traps&Power ups==
The stage can be filled with status traps like stun/shock and ice.This will make the players be more careful with their surroundings..plus they can use the traps as an advantage..Imagine push someone into a trap and then knock him off :P
The power ups will be speed +.I am thinking that a slow(speed -) should exist too with similar power up icon so if u dont have quick reflexes u ll mistook and u ll have disadvantage..Another power up it would be status immunity for 10 secs or something..

==About the idea==
Some players will find stupid and they ll say play a crash bash or a similar game..Why we need a different type of game in Colosieum?
Well with the same logic Blast shouldnt exist.You can go and play Bomberman..
I think its a funny and intersting game type..(Imagine the rage of some players when they ll be pushed out of stage :P)

==Epilogue==
If you like the idea then you are most welcome to suggest your idea and improve it..
This Idea is shapeless and in a beginner level..
