Revisiting the 2021 halloween board

The new league mechanic teaser made me revisit the 2021 Halloween board (https://i.redd.it/3f1huqdb7uw71.png). Looking back on it now, is there anything we missed back then?

Observations:

• Gigantic Atlas tree was obviously correct
• Add hunger to the Gauntlet event was likely a spoiler for the Endless Hunger Expansion boss.

Speculations:

• Unique items chase you could refer to Sentinel league, where we buff the Sentinel through unique items?
