From the same set of treasures as Marin the Fox

It's this kind of wording that makes Hearthstone so inaccessible.

Pretty good example, yeah. I mean - ok - the "fantastic treasure" pile is a known small pile that you can learn. But seeing this come up in a list of cards, is it any good? Who knows?

Deathrattle as a keyword for "When ~ dies" is atculaly pretty good though. And the first line is pretty clear, even if not the same templating as mtg uses.

I am wondering what the purpose of this set in multiverse is; just trasncribing hearthstone cards? Something else?

I needed a place to store my custom Hearthstone ideas. I have a discord I post them in, but I like having permanent storage

I agree on the accessibility issue. There are a ton of legendary minions whose ability boils down to "do a cool thing," where the cool thing is an effect from their secret pile of effects. But I have no idea what any of the options until I've seen them played a bunch of times. (E.g. Marin, Rafaam, ETC, Gelbin, Whizbang)
