This deck uses the same tactics as Hellfire Ritual, only it utilizes Demonic Dragon Mage, Mahoraga as a powerful booster over Blazing Flare Dragon as an attacker. I've altered the list with Gwynn the Ripper to give targetted retirement without having to neg yourself.  Additionally, this also lets Basilisk enable power boosts for Mahoragas on the field.  There's less 20k rows since I took out Seiger, but still the same access to powerful 21k+ rows.  And, honestly, the 20/21k deals are if you only soul charge or retire once, but this is a build that waits until the opponent is on their last legs, then goes all-in, so you will be doing multiples of each, to the point where the difference between a Seiger or Gwynn won't be that large.
