Blood Rite The Vampire deck stands out to me as the most relevant to supporting its corresponding type in a Cube, with meaningful support up and down the mana curve and notably offering some cheap white Vampires, which we really only see on Ixalan
Im putting on the L1 judge hat to see how afflict works, which cards have this ability, and why it is or isnt one of the best mechanics ever (it isnt)
If any of the D&D Secret Lair drops are going to sell out, it looks like this will be the one
That's not to say anything about the myriad of legendary creatures that come out of the Kamigawa block either
We spent the first ten plus turns amassing a magical army, where one players field usually consisted of 2x Doppleganger, 3x Mahamoti (one with Invisibility) and a Merfolk Assassin on one side, standing watch against the other players field of 3x Nightmare, 2x Royal Assassin and a Lord of the Pit with a Breeding Pit somewhere in play with two swamps permanently tapped underneath it
