Its one of the 3 you wont give up if they have a parallel/avery, so you can keep the dmg on board to move on your turn, but you also are probably down to your energy being mostly in the graveyard, so it isnt the best gust target for them, compared to malamar, and if they gust the munki, you can recur it and still have the damage on the bench for next turn
This gives players a reason to be confident when buying older and lets you know which cards wont lose half of their value being reprinted as a rare in a Core set
In Pokmon X and Y, players can obtain Aurorus by restoring the Sail Fossil, marking its first appearance
Thats fun if youre never attaching energy, yeah
Again, these changes are ONLY for the Alchemy format and Historic / Historic Brawl
