Chapter 16 of the manga has recently unveiled three new Shadow Paladin cards of unknown grade. It is uncertain if they will make the transition from manga to reality.
Unknown Grade/Shadow Paladin - Unknown/9000 Power/Unknown Shield
Speculation: The power is well within the limits of a grade 2 unit, is too high for a grade 1, and it appears that this unit was called while Ren's vanguard was Blaster Dark. As such, Rapier is probably grade 2.
Unknown Grade/Shadow Paladin - Unknown/10000 Power/Unknown Shield
Speculation: Going by the power, this could be a grade 2 or 3. Since Blaster Rapier can be seen to the side, and Dark is behind him, this appears to be another grade 2.
The Dark Dictator
Unknown Grade/Shadow Paladin - Unknown/Unknown Power/Unknown Shield
Speculation: Appears to be based on either Alfred Early or The King of Knights, Alfred. Definitely a grade 3. If it's based on Early, it probably superior calls Blaster Dark(or soulblasts/retires him for power, the Shadow Paladin way of doing things?) and if it's based on the King of Knights, all bets are off as to his skills.
