Okay, here's another repost, but I'll still share it.

It existed before. I see some insane, powerful combos. There will be a map like Ayla's – "this unit cannot be attacked." Unless this beauty gets taken down by a Bahamut.

It existed before. I like this map. It's nice as a support tool.

It existed before. Well, I don't see much benefit. Low-tier players will trade on the curve 1-for-1, and it won't remove anyone significant on evolution turns, it can't rush from the top deck, so it's not the best card in the world. And it costs gold. That's disappointing. The only thing is, it might be able to destroy wards, but it's still not the best card in the world.
Although people on Reddit are very excited about it, until I see it in action and try it out properly, for me, it's a free pass.

It existed before. This is a very good legendary. It can be used in a neutral build with high stats, and in a classic deck as infinite fuel for a weapon. Like.

It existed before. A good legendary, it's great that it only costs 2 more power points, and this will greatly strengthen Heaven's early game.

It seems like it existed before. What a cutie :3 A good card for Dashka and even for Dishita.

Oh, this one definitely existed before. It looks like a very good addition to many decks, including aggro decks and others.

I've calmed down a bit about this card after reading how people plan to use it. Look. Early game – shadow low-tier units for 1-6 power points. On turn 7, we put down Dark Alice. She bans all low-tier units, and then we draw Lucifers, Israys, Bahamuts, Zeus, and other insane legendaries. Plus, a neutral Mordekai. Shadow Valet incoming.
But such a strong anti-synergy with the class mechanic can't be pleasing. Why, why make a card that breaks the entire class, just to force people to build neutral decks? Ugh.

It existed before. Do you know why units with 1 health rarely see play? That's right.

To a lesser extent – because a fairy/knight/snowman/skeleton/ghost/mouse can trade with it. Maybe not all the cards on my list are popular in the meta, but when my opponent plays a card like this, I smirk and respond with May.
But seriously, you can try to tune it into a classic aggro deck. Just don't play it on the board against Forest/Runes.

It existed before. Well, it's okay. In the same vein as the lion legendary. It fits very well into the new neutral-amulet-Heaven. I'll risk calling it "beast Heaven."

It existed before. Including itself? Then it's not cool. Excluding itself? Then it might take off.
