Ive had relatively minimal exposure to Golos beyond the initial wave fueled by hype following Core Set 2020
A couple of good examples are flying and regeneration
Players likely didnt expect Gwenpool and Jeff, the Shark to make an honorary appearance in this Secret Lair
Looking for more recommendations
This alone makes it a powerful card, but if you activate the second ability on Academy Ruins, on your upkeep to put Mindslaver back on the top of your library, then you draw it on your turn, repeat the process, and play the game alone
Still, I tried cutting the weakest cards, especially the ones that are the least mana-efficient (Blitzball Stadium is cool but we have far more efficient ways of putting counters on things, giving evasion, and drawing cards for example)
