Kind of funny that in 2012, DXV thought Loan was the dud, but in 2020 doesn't even include it in the list of cards he'd remove. Loan has probably benefited from shifts in the meta over time.
Assuming DXV hasn't changed his mind on those six (Trade Route, Talisman, Contraband, Mountebank, Venture, Royal Seal), that still leaves possibly 3 others to remove. I'd bet on Counting House even if DXV said he wanted to keep it. I'd like to see Goons be replaced with something that's a bit less dominating. Vault and Hoard are probably the next weakest cards, so maybe we'd see one of those go.
