I have two holes in my card catalog and I'd like to know what they are. The first is between Samurai and Silver Idol. The second is between Slow and Sonic Wave.
I've defeated the story mode and I have the medals which tell me that I have all the cards without E rarity. However, it's possible that I've missed a side mission. (I recently found out about Najaran in this forum despite having the game for a year or two.)
For the curious, I finally got around to defeating a second story mode battle in the Kazatega stage. That gave me Sanctum Guard. I did not get Soltis at that time. However, I did get it after my first match in versus mode.
