Yu-Gi-Oh: The Festival of Time Official Discussion Topic

Like I said before Digi, Champion Cards are initially Synchros. They can be any synchro that isn't restricted. Champion Cards can later evolve and change into XYZ, Fusion, or Effect monsters. You do not actually have to use your Champion Card in duels. The reason synchros are important will be revealed in the story.

Duel Terminal is weird.

There's the first Duel Terminal, which was Worms vs Allies of Justice IIRC, then there's the second one with Gustos, Gishkis, Lavals/Flamvells (can't remember which), and Gem-Knights. Vylons appeared, then Steelswarms, then Evilswarms, and then everyone got pissed at the Gishkis for committing genocide against the Gustos, the Ice Barriers were unleashed, Sophia appeared, they kicked the crap out of her, and then Shaddolls and Nekroz happened.

I might want to participate if I'm allowed 100% fictional cards. Obviously I won't be using them against other people though.

And they'd be reasonable.

What I'm saying is I'd be writing my own stuff with multiple characters and only use custom cards in duels against myself. I'd use real cards when playing against other RPers.

Basic Rules:
Contact Summoning allows you to combine two monsters of the same Attribute (and/or Type) in order to power up one of the two monsters. In order to perform a Contact Summon, you need to select two face-up monsters on the field in opposite battle positions. You then place one Monster on top of the other. The bottom monster's effects are negated (this negation cannot be cancelled) and when the top monster's battle position matches the bottom monster's, the top monster may use the bottom monster's ATK and DEF during the Damage Step. This can be done at any time during your Main Phase with any number of monsters, however, this counts as a Special Summon, and can be negated as such. It also triggers any card effect that lists "Special Summoning" as its activation requirement.

Advanced Rules:
For Synchro Summoning, you can use either card's level.
For Synchro Summoning, if one card is a tuner and the other is not, you can choose it as a tuner or a non-tuner.
When Synchro Summoning, you can only use the top position monster, and the bottom is also sent to the graveyard.
For XYZ Summoning, the cards count only as 1 monster, but both are used as Material.
For XYZ Summoning, you can use either card's level.
For Fusion, the cards can be treated as separate Fusion material.
For Rituals, the cards' combined level is used.

Synchro Cards, XYZ Cards, and Ritual Cards can also be used for a Contact Summoning, and can be used in conjunction with Effect and Normal monsters.

If the two cards used for a Contact Summoning are a Synchro and non-Synchro, you can use both to satisfy the requirements of a Fusion Monster that lists a Synchro and non-Synchro as materials.

I probably should have posted this weeks ago, so people could practice, but I've been juggling a lot recently. Sorry.

How does a Utopia stack contact summon with another Utopia stack?

I'd suggest having to detach all XYZs material from one in order to stack them. Or otherwise ban Ghostrick Angel of Mischief.

Or the one card with an effect of "if this card has 7 or more Xyz materials, skip your opponent's next turn."
