Ok really guys, this isn't a hard question. But somehow no one can answer it. So let's try again.
the cards that come in HERO EXPANSION #1
ok..stay with me...
Are they duplicated in the random ccg like expansion you can buy here on BGG?
and yes i CAN buy a set. A few people that have a full set of the random cards have them up for sale.
Here is the description of the "random cgg" from its BGG webpage; it answers your question.
The Global Effects promo are a set of cards that are shuffled into the Darkness Spreads deck at the beginning of the game. As they are revealed, they will have various effects on the game, with 5 of the effects being good effects and 5 being bad.
Global Effects cards are also included in the Dragon Expansion as well as Hero Expansions 1, 2, and 3. There are currently 28 unique Global Effects cards, 14 good and 14 bad, that are randomly inserted into the expansions and card packs available via BGG. The expansions contain 6 cards, 3 good and 3 bad, while the BGG promo packs contain 10, 5 good and 5 bad.
You are able to combine Global Effects from the expansions/promos however you would like, affording a great variety from game to game.
