It's kind of an unspoken rule

mr trollface: yeah, if you do it, your just asking to get teamed on...

The Deals Maker:

he wants revenge, and doesn't care what he needs to do to get it.

on who?

Probably the Tyrant

Yep, he was kinda upset he couldn't kill the Tyrant, but considering slyceon's trying to bring him back, he might get another chance.

Collector: ok, let me show you why it's cheating.

Imagine you're fighting someone and your doing really good, then suddenly your on the ground with several holes in your chest.

That's why stopping time is cheating.

Overseer: I personally don't give a crap, unless I'm trying to challenge myself, or I'm training someone.
(he doesn't care because the Tyrant killed his mom, who at that time was the only person who cared for him, and that he cared about)
