@MenhirI've sent PMs to both him and Doc Doctor. The latter has apparently been sick. I'm waiting to hear from the former.
@manapool1Please pick a House. This isn't just summoning method, it's also where your character will be living for his next four years. With your current deck, I'd choose Dark Magician House.
In order to actually play with everybody else until I introduce shadow games and such or your character is like Saiou and can use a table that somehow makes holograms (which he only did once for some reason), your character is going to need a proper duel disk in order to actually play against others. This especially off since your character's dad works for
Nintendo Kaiba Corp.
I also definitely wouldn't call Sangan a card no one wants, even with the new eratta.
I don't quite agree with your deck running a Fiber Jar, especially since the rest of the deck seems to be able to hold its own plenty well without it. I'd suggest more cards that help bring out your ace monster/support it while it's already out. Maybe its own version of Dark Magic Attack?
I love the flavor of your character's Solar Legacy.
The spell/traps though I'd reword thusly:
Apple of discord
Normal Spell Card
Roll a six-sided die and apply the result.
1: Target 1 face-up card you control (except this card) and give control of it to your opponent.
2: Pay 500 Life Points.
3: Your opponent can look at your hand, then send 1 card from your hand to the Graveyard.
4: Your opponent targets 1 face-up card they control and gives control of it to you.
5: Look at your opponent's hand, choose 1 card, and add it to your hand.
6: Shuffle 1 card in your Graveyard back into the deck.
Necromancer's Circle
Normal Trap Card
During your Second Main Phase after this card is activated, target 1 monster in your graveyard: Special Summon it. Its level is halved and it is treated as a DARK Zombie-type monster. When this card leaves the field, destroy that target. When the target leaves the field, destroy this card.
I know the keywords help more but I kind of want to streamline the cardtext using the current self-correcting system just to avoid ruling issues in the future. This doesn't sound like much, but there was an issue that was raised when they reprinted Pot of Duality to use the word "Excavate" instead of "Look".
