Hidden Fangs of the Shadow Flowers
A deck revolving entirely around the various Plant-type monsters and the support it has gotten throughout the entirety of Sevens. Your main gameplan is to try and survive until you can establish an Etraynze the Shadow Flower Ninja on board with an Etraynze in grave, to then allow you to Fusion Summon Meika Etraynze the Shadow Flower Venus, which allows you to summon Etraynze back, and use it again - quickly swarming your field and putting up pressure. Shadow Flower Stance and Shadow Flower Return are both very powerful traps (though weak against effects like Grand Extreme) that allow you to disrupt your opponent's turn while ensuring an Etraynze makes it to your own turn. Gatling the Shadow Flower Shinobi, your other Level 7, is not that good, but the Fusion it goes into, Durga the Shadow Flower Stealth Submarine is a STRONG removal card, assuming your opponent has 2 or more monsters. But as Durga is simply our side option - not our wincon, like Meika Etraynze is - we opt not to play Star Restart, even though we are on a large number of normal monsters, as we can't really afford to give up the hand advantage for it - since Etraynze needs us to discard Plants to use her effect. Finally, for some specific applications of some cards: Ship of Seven Treasures and Graceful Charity help us put an Etraynze in our grave while not losing out on card advantage. Meika Etraynzeyes the Shadow Flower Lunatic may not have stats, but her effect effectively reduces the stats of monsters you couldnt beat over with Meika Etraynze to 0, and if you another Plant left over, you can use Shadow Flower Wish to resummon Etraynze, and get the Etraynze chain going again.
All in all - in a format with Gate Order being meta, this deck isn't all that good. Without side decks, it also loses incredibly hard against decks that are able to interrupt your Graveyard with their main engine - Bounce Control and Daedalus with Grand Extreme, for example. However, it's traps are incredibly powerful, and if you are able to properly start your combos, the Deck can be extremely powerful - but getting there can be problematic.
If it receives some of the anime cards it is missing, or if a Forbidden/Limited list shakes up the top tiers, this Deck could become good, but as it stands right now, it is just a fun, highroll-y, combo Deck, located entirely within your Rush Duel.
Nonetheless, enjoy the Deck to your heart's content.
