Some notes about the new rarity as well as a look at the new regional mat.
The video is just under 3 minutes and has a look at the new Regional Mat featuring Appolousa, Bow of the Goddess.
Some notes he mentions on the new rarity are:
-They will ONLY be available in the 1st edition booster packs. This means you can not get one in the Special Edition 3-pack blisters.
-They are “about 50 times harder to find than a secret rare”. Please note that this is not necessarily an exact number. However, taking Jerome at his word, you could estimate that at the estimated 2 secret rares per booster box, they would appear approximately 1 per every 25 boxes. Again, this may NOT be an exact number, nor is it official.
-No official name for the rarity has been given as of yet.
