"Treat also as Demon-Type in all locations and under all conditions. Must first be Xyz Summoned by banishing 2 DARK monsters (1 from your hand and 1 from your Graveyard), with Levels equal to or higher than this card's Rank, and using a monster you control with a Level equal to this card's Rank to this card as the Xyz Material. This card can only have a maximum of 3 Xyz Materials attached. Once per turn, unless you activated this effect during your previous turn: You may attach up to 2 DARK monsters from your Deck with Levels less than the Rank of this card to it as Xyz Materials."
I loved the idea so much I even made a SUMMONING SPEECH for it (ala 5D's):
- Birth, the flame yet ignited.
- Death, the flame long extinguished.
- Life, bathe in darkness one whose flame still burns.
- Through the power of the Black Trinity, open the black portal and go forth to build the Devil's Network.
Obviously there's a animation sequence followed up by someone yelling "XYZ SHOKAN!!" and the card's name.
The speech is written to reference (thus symbolize) how the mechanic works. One monster from your hand symbolizing Time before Birth (because the monster is in hand where they "live" before getting to be summoned). One monster from the Graveyard symbolizing time during Death (because the monster dead and his life has been extinguished, but the soul lives on). The monster that becomes the Xyz Material is symbolically bathed in the darkness from the banished monsters. Trinity is obviously because it's 3 monsters and then we keep with the whole "build the Network" scheme.
The first few (at least 6, not posted all at once) monsters I post will be based on evil/demonic versions of various existing Numbers, but I will (at some point) post some of my original design Devil Numbers.
