Many Discord / Black Hole decks are upgraded, but this deck really shines in an unupgraded environment (as in opponent is unupped too)
The reason that Discord BH is so good, is that it
quickly shuts down decks, while killing opponents reasonably fast.
This version of Discord BH attempts to consistently get a second turn discord for the lockdown.
there is an 75% chance of getting 3 or more pends on in your first 7 cards and 85% chance of getting 3 or more pends
that is a roughly 75% chance of getting discord in your first turn + draw
That is equivalent to a roughly 60% chance of
pure win, because second turn lockdown is too fast for many (unupped) decks.
The other 40% are struggles, which quite often result in a win anyways.
My all time favorite deck:

protip: if you get two pendulums (and have the discord in your hand) you can choose (you usually shouldn't) to hold onto the cards because there is a slightly greater than 50% chance you will get the last pendulum.
Another good Discord BH by Spielkind
this one focuses on gravity, getting a 3rd or 4th turn discord (thats not good enough, for example he lost the match that this happened in)
