Artuad, super interesting but powerful card. Fecusya, not that interesting but a card that makes rain work, yet still pretty powerful. Simlas – ST carpet bomb for specials, cool, but man is it powerful.
Why are these cards not tagged with Devotion mechanics? I am not even going to get into suggesting what they could be because there's literally dozens of ways and any of them would likely reel them in.
Want your OP card? Sure strip your deck of the Korathis, stop with the Mushy Truffle spam. Save your Wanderers for another deck.
It would be nice to keep these unique abilities intact and not butchered but you can't keep these cards in the game as they stand because they are not even remotely on the same level as any other card in the game for the same prov cost. With the speed of your patches, you'd be buffing legacy Gold's until 2025. Turn em Devotion and ideally we'd get more variety too since the same Neutrals wouldn't be in every deck.
