Magenta's challenges of death

Magenta: Well hi,im back from the dead and im here to host this new show called magenta's challenges of death.

Magenta: You may ask,what is this anyway ? Well,20 contestants compete in different challenges,but heres the twist. in every challenge,the contestant who places last dies(and doesnt recover),this continues until the final 3,when stuff I shouldnt be telling you starts to happen.

Magenta: So yeah,thats the rules.
