I basically remember Heros and dark whole and build from there. I learned about ZERO, dark law and Dark Hole Dragon and thought there might be a way to make that work as a sort of dead man's switch. This is a first draft so I am welcome for advice.
The basic engine is a basic dark law heros deck. You have your Stratos combo to get DL on the field but I added more heros and chances to get ZERO out as well.
The the DL deck itself is an effective deck but what you want is to get DHD in your hand or grave and then either DH the board to get him out, have the opponents take a monster out to activate his effect OR get ZERO on the board. Zero if killed will wipe the board activating DHDs effect and you now have a free 3000 atk monster. If you have DL on the field as well all their monster are banished. It theoretical works by making your opponent have no good options for killing anything. You run ash and some of the extra deck to adapt if need be.
This really is new to me and I am having people look at this as well. I have been told DHD does better with other cards but I like Heros and if I can get DHD to even function like I want in it I think it is a win. This is also the first deck I have posted and have no idea how any of this works so please understand I am learning. Thank you and maybe this can give you some inspirational to build something goofy like this in the future.
