Pretty much exactly my thoughts about how I'll use these, though I don't consider any of the cards truly trash-tier except Morrigan.
Definitely Kalimos and Putricide aren't going to be tier 1 or even 2 but I've played a spells and secrets hunter control list in the past that works well enough and while I mostly play elemental mage, I wanna give elemental shaman a shot w/ Kalimos and some of the cross-over cards I already have. I suspect you are right and it will just be too slow or outclassed and ultimately end up frustrating to play.
I'm currently playing the Woecleaver/recruit warrior Deck_Fiend pointed me to above, and while it is a little bit too light on card draw, it is pretty fun and funny to blow out greedy highlander priests with a board full of rags. https://www.hearthpwn.com/decks/1364213-63-winrate-w-guide-the-dimensional-boomship
Tog/Azalina druid is outdated for sure and I won't be playing it anytime soon but the nice thing about Wild is that new cards can rebuff old combos or archetypes which is why I'll hang on to Azalina since I already have Tog, who knows - the combo may make a comeback or a new combo may appear involving the cards.
You can meme with Noggenfogger but it gets pretty boring fast and there are more enjoyable meme options - I used to have the card and IIRC played it in a Yogg RNG YOLO deck but it wasn't as much fun as I thought it would be and dusted it after the Yogg nerf. Dusted it again just now, RIP.
Thanks for sharing your thoughts and the vid. Cheers!
ha ha, no way. right after I commented you about Dr morrigan, I unlocked the forum title "dr morrigan. pretty trippy.
