how much change does Red-Eyes fusion and Red-Eyes Alternate bring?
I mean... can't we just pimp up the red-eyes slash decks we used back in the day by replacing the Polymerisations with Red-Eyes Fusion, and the wyverns with Red-Eyes Alternate?
Do we need D.D. ans Sphere Kuriboh for our Red-Eyes Decks in the current meta?
We don't, in fact this is actually one of the bad exemple of red eyes deck i think.
It depend on the player but in my case for exemple i use Buster Blader for the warrior monster and i don't use kuriboh at all in it either as it takes the spot for card such as Return of the red eyes and red eyes spirit. You then want to have at least one Red eyes Archfiend in the deck because his effect.
I don't think there's going to be enough space for Archfiend of Lightning after Black Metal Dragon is introduced. Isn't it kind of slow anyway? I guess the payoff is really good, but I would rather play it in a dedicated deck rather than just splashing it into this one.
From my experience Sphere Kuriboh is a good choice since this deck tends to clog your spell field with equip monsters. And for the same reason, I'm not even sure if Black Metal will be a worthy addition to this deck.
I'm having doubt about black metal dragon as well.
From what I envisioned, BMD will further increase the consistency of the already-consistent RE deck, but I felt that the equip effect +600 ATK is pretty mediocre, since that it must be in hand/field to activate that.
