Another great guide. I really like Akane and I'd place it in A. I would also point out that it might be better to keep Fenmoor Haunt at level 8 or 9 instead of max level. For most games I'd prefer the extra attack stat. There are certainly situations where Scavenger is better, though.
The only weird thing I find in your rankings is the inclusion of 2 promo cards: Mantaroth and Baron Fyatt. I could see including Mantaroth and Grimbardun Smith, since they were the pre-sale promo cards, which means they are directly tied to the core set, unlike the rest of the promos. However, Baron Fyatt should not be there 100% and if Grimbardun isn't, Mantaroth shouldn't be either.
Doh! Forgetting Grim Smith is really a terrible miss! I'll add him in right away, nice catch!
Yeah I thought that about Fyatt and decided to place him with the core set rather than with the Hall of Legends, but I suppose you're right - makes more sense to stick him with the promos. I'll remove him here and add back when I do that list!
Thanks again for the eagle eye @olaf.gui!
You're welcome!
BTW I hate to do this but Grimbardun Smith is a rare not a common 😅
