Time for a new map revealer.

deal 1 damage to all enemy followers reduce the countdown of your amulets by 1.

Exactly what the Hive needs – a countdown reduction and AoE. And to smear the enemy's face with jam.
Seriously, it might find its place in decks, but it's not amazing, more like a niche, maybe in Seraph against aggro, etc.

fanfare: summon a poison snake
at the start of your turn if you have 2 or more poison snakes combine 2 of them and become medusiana.

Rush Bane Can attack 3 time in one turn.

Flame-n-Glass tier. We'll probably never see Medusiana anywhere, and even if we do, it's something on the level of Sword Saint Alexander, and Blood already has plenty of hard removal and AoEs. As a card itself, it's decent. It might work in aggro, as the 4-slot is usually empty, and weirdos run all sorts of nonsense in it, so this will be something decent. It's also interesting whether other poisonous snakes will hatch from other cards.

5 5/4
Fanfare: ambush until the end of the opponent turn.

The worst Kunoichi Master. That one summons two bodies, and this one summons only one, which means less resilience to random removals and other things. Plus, the ambush ends on the next turn, not permanently. It's okay for Tier 2, but for Constructed, maybe only for weirdos in aggro/tempo.
I suddenly thought that Cynthia might follow this, which isn't that bad, but Cynthia is already overpowered by Ephemera, so she's mediocre on her own.
Ah, it's not getting any love in the new expansion :(
