To start off, I want to discuss why I chose Genesis cards for this article. One reason is the supply of Genesis cards is limited and the cards are deflationary in nature given players wanting to forge them up to shadow and higher levels. Due to this even if these cards are not that playable, there is a collectible component. The other reason is that these cards are locked and cannot be nerfed. There is only upside with new releases coming out to assist with the value of these cards.
Runaway Trebuchet($0.68): This card seems like an inferior archangel bruiser. Blitz but with an added roar ability of dealing 2 damage to a random enemy. That is almost like the overkill the bruiser gets when frenzied and could be used in blitz control war decks in the future. Pairing this with the shield relic would offer more use for this card.
Laertes Vendetta ($0.78): Deception is not really a relic heavy team right now. If there was to be a buff on the order relic or a new powerful relic for deception in the future, this card could see a huge boost. Even without this, hidden rush deception is pretty powerful and being able to remove a large armored tank with one card is a nice boost.
Vine Armour ($0.86): This card is probably one mana cost too high to be used a lot however is a great counter to aggro war decks. With one and two health monsters throughout war, this card could take a few out easily and make your opponent think twice about hitting your face. A great addition this card could use would be a mana boost card early in the game for nature similar to what magic has.
These is not an exhaustive list and I think any genesis card could be seen as a great investment if you believe in the game for the long term. That long term approach will produce the greatest returns I believe for Gods unchained cards. If you liked this post, please upvote or comment with a different set I should look at in the future.
