"spiritual successor to the From the Vault series"

Not a fan of being a replacement but I otherwise like the idea of that. And really all this seems fairly cool, even if I'll likely never touch Battlebond outside of cards good in EDH (because I really only play limited and EDH).

A new booster product, featuring new cards, designed for 2-headed giant play? I am looking forward to this already!

Huh... china specific duel deck.
Well, I'm down for some mythology exploration, but it's a strange target. I wonder if the characters will actually get any exposure outside it.

Battlebond will be fun if only for a new setting.

Aaaaaaand signature spellbook sounds like a thing aimed towards me, but until I get to see what's in it, I won't call it worth the price.

Also, the key art for Core 2019 is out and it shows Nicol Bolas.

I like the wwe flavor of battlebond but 2hg isn't an exciting format, it's just a way of adding more players without unbalancing the game

Well I feel that's the point of this. To make it more exciting and popular.

The story is clearly going back to Ravnica post Dominaria for more Bolas Belligerence Battles with Belaren and the Boys (and Girls)
