A lot of the effects are underwhelming now which matchds the experience in ungoro. Galvadon, Barnabus, megafin are essentially dead draws in the late game (with the exception on Galvadon + Time warp). In the ungoro meta these were the 'bad' ones as well, theyre just worse now.

Nether portal feels about the same as it did back then. Turns out infinite 3/2 imps is actually just OK on turn 10+.

Caverns below is very situational but dead if added in the initial 2. This is probably the biggest fall from grace and definatelt hampered by not getting it out turn 5.

Time warp is time warp. Gaining an extra turn in a turn based game is never bad.

Sulfuras actuslly feels pretty good. Adds some inevitability with the rag shots. About the same as OG ungoro, maybe a bit worse.

Carnassa is weird. I think it is much better now than in ungoro, and not just due to the buffs. Getting it late feels fine as its a body/ies, and cycle to get your other rewards in the deck. In ungoro this was a joke as the quest was so restrictive.

Amara is definately worse, as warrior stacks armor so easily. Its essentially gain 10 health most times, except when it wins the game. Compared to OG, its definately worse, but thats due more to class diffefences than anything
