A short clip showing what the new rarity looks like has been revealed. This new rarity will be introduced in the “Deck Modification Pack – Hyperspeed Rush Road!!”. The 3 cards that come in this rarity are the reprints for Sevens Road Magician and Rush Dragon Dragears, as well as the Rush Duel version of Blue-Eyes White Dragon.

I suggest just checking the clip in the original tweet because still pictures don’t do it justice:
