Nemesis archetypes and the most unique nemeses
Spoilers for Legacy of Gravehold - worst ones are masked.
I own: Core, War Eternal, Shattered Dreams, Legacy of Gravehold, The Descent
I've recognized that almost all nemeses follow a fairly small set of archetypes. I've not played all the content, so I'm curious what your choices would be for the most unusual and fun nemeses. There are subtypes like token buildup, temptation, and economy focus but these didn't strike me as definitive enough to be primary archetypes. None of this is to say that having archetypes is a problem.
Corruption: These add negative cards to your deck, and are many people's most hated nemeses. Crooked Mask, Rust Amalgam, The Wailing, The Blight
Minion Rush: These hit you early and often with piles of enemies, forcing you to focus damage even earlier than usual. Bishop of Scrolls, Mother of Rust, Rust Superion, Paradox of Myth, >!Mist Revealed!<
Damage Control: Thoughtlessly damaging, not having enough instances of damage or choosing the wrong targets can spell disaster. Carapace Queen, The Coven, The Wrath, Magus of Cloaks, Hollow Crown
Snowball: These have some mechanic to directly advance the deck faster than usual or something else that will make long term defense even more impossible than usual. >!Bishop: Returned, !<Umbra Titan, The Infecter, Gate Witch
Glutton: As its namesake, these interact negatively with the market. Prince of Gluttons, Griefweaver
For my choices, I'll say Fate Shepherd which does >!some quirky temptation and deck swapping tricks!<, and Paradox of Myth and Bone which is >!two nemeses at once!<.
Among what I own, only The Wailing is truly an economy nemesis. I found it refreshing to be allowed to focus on something other than desperately pushing out damage.
