Heh, this looks like a fun section.

Alright, to show willing, I'll start off with something I designed a while back.

For those of you in the same RP as me, this was the custom card I finally built for it.
I never got to use it, and have no idea if I can still do so.
But whatever.

Sky Scourge Erzsabel.

Light / Fairy / Eight star / Synchro / Effect

1 Light or Dark Tuner + 1 or more Light or Dark non-tuner monsters.

This card's attribute is also treated as Dark. If you synchro summon this card using one of the following tuner monsters, it gains the appropriate effects.
- Light Fairy: Negate the effects of all Spell cards.
- Dark Fiend: Negate the effects of all Trap cards.

Attack: 2750
Defense: 2000

So yeah.

I think that card is pretty stable. Nice effect but i'd lower the ATK just a tad bit. Not too much, under 2700 but over 2500, if you get what I mean? Everything else is fine I have no objections to it. Overall, 9/10 for OCG compatibility. 10/10 for Realism and creativity
