This deck needs serious limitations, it can use the graveyard as hand, summon levianeer for destroying 2 cards/discard 1 from opponent hand, mill 10 cards and synchro summon and all this in the first turn. Of course Konami already made profit from this and they can limit Levianeer to 2, because it's no more in the selection box
Shiranui isn't OP at all. At least the deck never OTK on turn 2, giving you a chance to fight back. Decks are much more broken nowadays with all kinds of stupid turn 2 OTK & broken turn 1 board with balance.
Lupine got nothing to do with Metaphys. It is not a card related to Metaphys archetype, just that Metaphys abused it. Charge of the Light Brigade is a Lightsworn card, it was abused by all kinds of broken decks from Crystron, Witchcrafter, Thunder Dragon.... Komoney is correct to stop people from abusing cards out of own archetype.
Limit charge of the light brigade AND raiden to 1 to deal with lightsworn engine forever. This engine is abused by tons of decks and will be abused by tons that will come in the future.
The engine is the problem. Hope konami doesnt start limiting every single thunder dragon monster. It reminds me how they tried to stoped invoked engine by hiting all elemental saber and fire related cards...
