Gandalfs abilities kind of remind me of reading spells from scrolls in Dungeons & Dragons
In addition, one of the new One Piece Odyssey cards in Emperors in the New World [OP-09] was a Leader card: specifically, a Green/Purple Lim card
Youll be able to get a standard, fully playable, Ultra Rare copy of any of these 18 cards to put in your Deck
Protection from humans is also very relevant, as there are a ton of humans in this set
Other DARK Fusion Monsters worth considering are those from the "Starving Venom" or "Fusion Dragon" archetypes, whose members are either related to or are also members/support of "Predap"/ "Predaplant", effectively serving as the theme's boss monsters
"Mill myself": In this deck I can also use an "automill" strategy, as Golgari's decks do: this is useful in order to draw Artful Dodge (considering that I'm pretty sure to have a Wight of Precinct Six or a Consuming Aberration in my hand or in the battlefield), then use its flashback ability
