Now it makes sense while Super Polymerization didn't go to 3 in the OCG. Or at least two reasons; one is they don't like side deck staples at 3(as it homogenizes the game), and two is that it would make more sense to put it at 3 to match the new mechanics.
Also, this is awesome. I can properly play my Possessed Bandit Keith deck without all the extra Linking stuff eventually. I might be able to move it to Advanced soon enough(though not till Harpie's Feather Duster comes back. I can tolerate a lack of Cyber Jar, at least). Most of the cards work fine otherwise. I don't need Graceful Charity, Pot of Greed, Giant Trunade, either. Super Polymerization is at 3. I run generally 1 of each fusion(and the HERO attribute fusions) as is. Emperor Dragon's back at 3, though the erratum does matter. But I can't really run its Sky Scourge counterpart anyway, so eh. I might be able to, though... if I can throw it into the GY for Phantom of Chaos? Plus I get extra stuff from my Shaddolls. It's worth testing. Stratos I never focused on since I used mostly Prisma anyway for the Cyber Dragon parts. But I can also run Rank 5's again.
...I would also lose Shock Master, who is a big boon. Hrm. I am still going to run all the Solemn counter traps with one Pendulum Monster, probably. It also works fine enough for a Level 4, I guess? I don't think it was a Normal Monster with just a Pendulum effect, so Rabbit doesn't help that. These changes do however help a different Advanced deck I have. It losing Norden was really painful(but that's really all that hurt it, besides Terrortop's limit... so that kind of matters, since it focuses on Machines and all).
