Attack: 3N
Wall: +4N
N = #Soldier + #Holy cards in hand

I don't like this change. I propose to make this a separete card or revert to the old effect

Old effect:
Replace all non-holy soldiers with holy cards of the same rarity

You broke my Alastor deck!

I loved playing Guardian Angel early game with a handful of soldier cards and a dream shift on hand.

am I the only one who thinks this card costs too much? :)

The cost makes sense given that part of its effect usually costs bricks. Most times, building wall or tower from gems and/or recruits comes at a higher cost than if it were accomplished with bricks.

That being said, I don't have a Holy deck or one that focuses on Soldiers, so I've never used this card and can't judge it from experience.

I used it a lot. I have 77-25 with Holy/Soldier deck with this card.
This card in its pre-nerfed version was ridiculously overpowered, along with Zealot. Now it's a bit stronger than Forest spirit, but also a bit more expensive. Or you can think about it as about more defense-oriented version of Gate guardian.
In other words, it's fine and doesn't need buffs.
