Excellent, I no longer have to use 4* Zephiel for the Armoured Monthly quests.
Black Knight's stats are very similar to Atk Up/Res down Amelia but damn, BK's skills and weapon.
Seriously, they're practically giving away a very powerful unit that they easily could have made money off of.
IntSys are just trying to get us all to start forming teams out of other units for a while now that they're just handing out great units for us to do so. Sure, Horse Emblem will still run riot, but now we can all throw in Flier & Armour Emblem too.
I'm waiting for them to do something great to Colourless units, then my dream of #TeamArrow will be fully realised!
