Still, the main question is about RE Spirit, and RE Fusion's name changing effect disappear when the fusion monster goes to the graveyard, meaning you can't revive this card with RE Spirit even if you used RE Fusion to summon this card.
I "easilly" summon this card most of my duels. I've got a deck in construction yet but it is working nice at the moment.
I use 2 Red-Eyes and used to use 1 Meteor (I need those fusion material cards which can be used as any material to see if it will work nicely).
I "easily" summon it with my "Blue Dragon Summoner" and "Wonderful Wand", my oponents some times quit the duel. My deck is still missing some cards (hard to get from packs) to make it better.
I have Red eyes B. meteor dragon in my extra deck and Red eyes B. dragon on the field with Meteor Dragon in my hand, but when I play polymerisation it won't let me activate any effect to summon Red eyes B. meteor dragon. Am I doing something wrong ???
