Black Seraph, Gavrail can be found in G Booster Set 07 - Glorious Bravery of Radiant Sword. Being in RRR and SP is quite reasonable for this G unit. Honestly, Angel Feather players will definitely run this angel. Why? As for the new Angel Feather special ability Rescue, this angel will heal and deal you 2 damage in a turn, so you can have like 5 times of trigger check during the turn you Stride this angel. And of course, your rear-guards will get more power from its first Auto skill. Gavrail will really make Angel Feather deck more powerful. Boo yaa!
