Tall Woodland used to be a thing in HC before he got nerfed
Beast Bran (was ok)
improved Coral Bran + Lippy (tier 1) but he got nerfed so soon that I didn't suffer long enough to remember it well. Who plays Lippy now...
Witcher NG was played but not sure what tier it was. I mean the oldest incarnation with pre-nerfed: Eskiel Pathfinder, WitcherTrio, Ciris (all of them) and pre nerfed the guy who shot2 whenever you played a Witcher, so a weaker version of this SY guy...
Reveal Morvran when Reveal was actually an archetype. At one point it was strong, but got nerfed...
CC Morvran 18 provisions -- with just Witcher trio (Letho...) and other midrange units, every NG was the exact same back then
pre-nerf Crah+Wolfsbane
Lock Usurper - before nerfs and leader-provisions he had the penalty of having 0 mulligans. Before Purify, lock was a thing, and very annoying. Not sure what tier though.
Tier 2(bottom) Movement Morvran - I remember it because I invented it he he. Was quite good I think. Freddy made a video about such a deck. Before DragonsDream nerf.
Traps Eldain -- not long ago. With Summoning Circle. I made this deck myself and I think it was tier 2 too, very powerful. I had like 35/40 matches won. Now it's nerfed and won't work well in version I created. But modified SirPumpkins may be fine without Summoning Circle, idk.
Blue Dream Meta -- I mean, this card was everywhere.
The very start of HC?
No unit Eithne (Spears, Shields artifacts with old Sihil, pre nerfed Epidemics...)
Sihil Greatswords...
No unit Woodland... those were unfair, annoying, yeah.
...and many many more but not sure if anyone read this and this post became quite long-ish
//note: all of what I wrote is Homecoming.
From Beta I played 1 week but remember: Nekker AQ, Strengthen Ciri, Resilence Dwarves, discard Francesca, spell Dol Balthana Sentry that buffed 3x to 17... Strengthen Greatsword + Ship that dmg_ally+buffself
