Erm, trophies deconfirm?
All the characters in-game are trophies/action figures according to the game's story...
The whole "npc appearance means deconfirmation" rule is BS anyway (assist trophies excluded since they have been confirmed to be deconfirmations), but a trophy appearance INCREASES the chances because all the playable characters had trophies, multiple trophies in fact.
The only thing that the other npc appearances have to suggest that a character who has an npc appearance will not be playable is precedent, it hasn't happened before. Trophies don't even have that.
First, Sakurai would never leak a character like that. He'd show off the character before the trophy (this is also why I say it hurts Krystal's chances). Also, any character who had a trophy was the Brawl model for the character, and also the art work for that character.
My guess on this trophy is that this trophy is meant to represent WW Link. Remember though, that it was "Cat Eye Link" in the poll so the name doesn't mean anything. This is probably the generic trophy given to the character. Also, it's a mock off of Link. Just like Racoon Mario is a knock off of Mario.
But trophies never increase a character's chance. It always lowers it. You can always say "Oh, there may be multiple trophies for that character" but it is more or less there is one trophy. The exception has so far been only Mario and Luigi. The trophy, "Regular Clothes Link", seems to be a generic WW trophy. It's presents is for representing WW. We'll have to translate it, but it may just recount the game. If that is the case, the character is 100% deconfirmed unless the played character is "Regular Clothes Link" but that seems unlikely.
