Hehehe it’s complete finally
I'm guessing that triggering Flashing Blade with 50 Spd is easier than triggering Heavy Blade with 60 Atk, especially with all the 40 Atk Armor units with their Atk superboons running around.
The only ones that could potentially out-speed him is Karla and (maybe) Ayra, while you got Grima, L!Hector, Effie, W!Chrom, etc. with their sky-high Atk.
Nice job, he (would) look great but no offense, Ive popped a lota +10 Ravens with Nanna's Pain + adult Tiki in arena. I used to think he was scary when I first saw his Basilikos refine and builds when it first came out.. but after first destroying Lubu's team of Ike/Raven/Julia/Ninian.. he didn't seem so intimidating afterwards
