Solomon Muto first appeared in the original series of Yu-Gi-Oh! He owns a game shop and he's the grandfather of Yugi Muto. Solomon Muto is the one who gave the Millennium Necklace to Yugi Muto. He also made several appearances in Yu-Gi-Oh! GX.
Slifer the Sky Dragon's name is completely irrelevant to the plot. It has no actual relation to the Egyptian God Osiris, it's just named after it. It's not like he's the only God in the Dub that isn't named after an Egyptian god anyway, since Obelisk isn't in either language.
Well coming next month or so they are adding the legendary exodia incarnate to the game so if they were to add Solomon at the time of the announcement for that card would be a good time, you know like you have to beat Solomon to be able to achieve the card or something like that lol I already know it's not though they're gonna do something with Yugi at level 50+ to be able to get the card
And he received a new one for his lines in Bonds Beyond Time and Dark Side of Dimensions. I doubt either of Maddie's major characters (the other being GX's Sartorius) are out of the running. The only thing that makes me question Solomon is Yugi having an Exodia skill already.
If he had been unlockable, we would have gotten his Exodia cards without using the skill Granpa’s cards. Wait a minute if we put Exodia into Yugi’s deck with Granpa’s cards skill, then he would have 2 sets of Exodia!
That was Gozabura Kaiba's ace though. What about when they add him and Noah. I mean F***ing Espa Roba got in somehow so they will probably eventually get around to Season 3 characters (waits eagerly for Seal of Orichalcos before the extra deck becomes to important to exclude from the meta).
They only added Espa Roba because of Jinzo being such a popular card. Also, at least Espa Roba is a unique and somewhat fun character, whereas I'm really not sure what they'd be able to do with Solomon. Maybe if they just added Solomon as an NPC that you can buy cards from, kinda like the card trader but have him trade Legendary Duelist drops instead. That would be pretty cool.
