GHNA continues the PAD Appreciation Celebration by giving all players 4 special Medals that can be Monster Exchanged for various 7-star GFE. This is incredibly exciting as 7-star GFE are arguably the most valuable cards in the game as they can be used as leaders, subs, inherits, or Trade Fodder.
Furthermore, GH tends to give these cards the most love with regular buffs and new evolutions that can potentially push them back into the meta spotlight. As such, it is in your best interest to choose the card that is best for you but to also remember that these Medals do not expire.
This means you should not Monster Exchange until you know you have a dedicated use for that respective card as it feels pretty terrible making a hasty trade only to realize you need a different card badly a few weeks down the road.
As a general rule, it is almost always best to acquire a card you have never owned before as it may open up new possibilities as each card is unique.
With this in mind, I will be going over all the notable Medal options each week when they are released.
