Yes.
I'm sure the pages will be made once the amiibo physically come out. They also did announced everyone but Sora getting their amiibos soon, with the Sephiroth and Kazuya's amiibo being displayed recently.
Hmm I'll explain what I do know about each...
Shovel Knight Gold Edition:
Gold Shovel Knight is a game stop exclusive amiibo that released at the same time as the Shovel Knight: Treasure Trove Amiibo 3-Pack. Its armor is brass colored with anything beneath being colored bronze, different to other gold amiibos. It works exactly like the original with the obvious exception being recognized as "Gold Shovel Knight" when scanned in Shovel Knight Treasure Trove.
Trivia:
The developers of Shovel Knight confirmed that one of the main reasons it was released was for those players who missed out on the original amiibo.
There were two different versions shown of this amiibo before it was released. One was a fully chrome brass and later on the other was a placeholder with the armor being a blunt yellow and anything beneath being a blunt brown (similer to the king knight amiibo and the ornate plate armor from the game).
This is the first store exclusive amiibo to be added onto switch box art.
The cards:
Yugioh Rush Duel Saikyo Battle Royale is a game exclusive to japan, you could have bought some blind bags with 3 random amiibo cards as a limited time promotion, there are a total of 7 different cards to collect.
I don't know much about the other apart from the fact that they do exist and again are marked as amiibo. oh and it's also a japan exclusive.
I recently found this place but I have found a lot of things missing... When somewhat known amiibo like Gold Shovel Knight or the completely unknown amiibo like those Power Pros and Yu-Gi-Oh! amiibo cards (Yes they exist and yes their packaging makers them as amiibo so it does count.)
But eh this place seems like it's decayed which is a shame but oh well.
Sadly no, the best time for him would have been M&LSS+BM but that time has clearly passed.
(Which is a shame since he's one of my favorite Mario characters as well.)
