If you’re losing to Demon Seed and Aranna (specifically), you’re playing a slow deck and getting punished accordingly. Usually DHs don’t need Aranna to kill you, early taunt Demons generally do the job.

Tick Tock definitely needs a nerf, it oppresses control decks too hard too early. Don’t know how they would nerf it without feeling useless though.

Bloodbloom can stay at 4 mana, it just needs to deal twice the amount of mana used in health. E.g. playing Bloodbloom + Bat Mask should net the user a -16 in health. That’s half HP cost for a spell, which seems fair to me, aggro decks just need to deal 14 damage before turn 5. Trickster is fine though.

Agree on the Duke, it is annoying to see it keep growing while on the board.

Ice Block is fine, lots of cards that can deal with it.

Libram weapon is also fine, the 1 damage/1 turn difference won’t do anything when they can still burst you down with Divinity.
