So Tutor Monstersare like Ritual Cardsonly they are Monster Cards.Obviously the Syncro Monsters namecomes from ashortened version ofsynchronize.
Kind of sounds like they are running out of original ideas. They have "contact fusion" for the Neo Spacians and now these Tutor Monsters who are basically fighting Rituals.
Can the Tutor monster itself be used as a sacrifice to summon the Syncro Monster? It would make them a bit more useful as I see no point to have them otherwise.
So any Tutor or Syncro cards revealed or are they saving something for the end of Yu-Gi-Oh! GX?
Oh, and as for the Genesis title, it was most likely scrapped. Before any new show gets finalized they go through a few "temporary titles" until they could actually think up a good name for it. Though since the Boosters are shown with the logo this new "Yu-Gi-Oh! 5D" might be the permanent title, but there is always time for a change before printing actually begins.
Now the rule would apply this case in this way:
you summon junk syncro and by the effect you also summon a lvl 2 monster, now in the field you have a total of 5 lvls [2+3] so you can summon junk warrior from the extra deck.
[Extra deck is like the fusion deck, that is the place were you keep your syncro monsters]
Edit: sorry, i made a mistake, it's synchron monsters and tuner monsters ^_^;; synchron are the white cards and tuners are like spirits and toons.
