Huh, you had more spell/trap hate than I thought. Guess you just didn't draw into it during the test. Whenever you make a deck, you need to make sure you only add a card if it helps what you're trying to accomplish, not just because it's part of the archtype or the same attibute as the archtype. Well, what are Flamvells good at? They have a Shura-like synchro system, plenty of tuners, and best of all Rekindling, so they're clearly meant to synchro like there's no tomorrow. Tengu's just what the doctor ordered ti make Flamvell more consistant AND explosive. Your standard Flamvell engine is this:
3x Firedog
3x Magician
but Hedgehog is good, and I like Shooting Star Dragon and Red Nova Dragon, so we'll add Baby and Poun. I personally use a single Grunika because often I don't have enough non-tuner flamvells in grave. Flamvells work just as well from the grave, so lightsworn are very helpful. We use Tengu though, so they're not as needed as before, so 3 Ryko, no more ls and no Charge. Here's my build for the new banlist:

Flamvells definately got better with the banlist. They weren't even touched, and with Heavy back they're that much harder to prevent from swarming. Starlight's in bc I still use traps and it's fun to use against Dark Hole, Heavy, BRD, Icarus (which is back at 3), Offering, and others. This may change a little. Dustshoot seems like an important card this format, and I was using Horn of The Phantom Beast to run over stuff more effectively, but with Heavy and 3 mst I took them out. I still may use them. Dandy I'm considering so I can make Shooting without Rekindling, and he's just good for synchro spam in general. And I miss One For One :/. And to answer your pm, no, I do not care if you use this as your main deck. Spam it all you want bro
