With these additions, I hope to expand my deck's options as opposed to just running 2-3 of everything in the archetype in one deck. There will be more additions in the future, but for now, I feel like this will do.
Thank you for your time as usual.
EDIT: Massive Balance Changes;
Gate Attendant can only search a Pand or Pend on Normal Summon
Rune Priestess requires you to shuffle a card from your hand as a cost for her effect
Gate Magician is now Level 8 and her ATK has increased.
Gate Abomination's ATK gain has decreased to 300 but is no longer OPT and lasts until my next turn
ALL ED MONSTERS (and the Ritual) have a kaiju clause for their sub-archetype (forgot to put that in the forum post, my bad >_<)
Ritual of Corvus and Oath of the Demons' banish effects are no longer dumb as all hell
Void-Eyes can now only be Ritual Summoned with the Ritual Spell posted (no generic usage allowed)
Sauriel now gains the ATK of the banished monster + 1000 instead of double the ATK of the banished monster
Venyr's effect no longer lets you activate the S/T placed the turn it was set
Forum Post Edit: There are only 12 cards, not 13. (I miscounted.)
Final Edit: Changed some colons, semi-colons, and commas so the effects are correctly structured.
