Fiddling Around with: Chaos-End Master

I was playing around with the new Dododos, thinking of how nice they were, and I was brainstorming for more options on how to search Gasser to the hand and summon Witch to get him face-down, instead of relying on a searcher+Tsukuyomi (which was, for those who want to try it, probably the most efficient way to play it). One of those searchers was Chaos-End Master (CEM for short). CEM special summons a LV5+ monster with 1600- ATK when he destroys a monster by battle.You may think that this card is a +1 (assuming you used a card to boost his 1500 ATK) but pretty hard to pull off and without any real result, but that's not it.

Ultimate Leodip's Infernity Guide

As requested by Thomas, the winner of the 30.000 Visits Contest, here it is a full Infernity Guide.
As an Infernity lover (and pretty much half-veteran, since I played it in lots of builds with lots of techs at least once per format) I'm more than happy to write this one. What's more, this'll be a guide that I'll update, that's why it is the "ultimate" guide, it'll always be updated as long as I discover something new about Infernities that I think it's worth writing.
Let's start it: (cutting post because it is way too long)
