It's still Promo Week and today we have the redundantly
named Granblue Dragon Undead, Skull Dragon. He can
revive himself from the drop zone by sacrificing a unit
that's Grade 2 or higher, and he can attack for 13k at
the cost of dying (again).
Okay, unlike the last 2 this one's actually okay. He's
Palamedes if Palamedes was actually balanced. This
Dragon-man can pretty much be teched anywhere and you
should still do alright with him. Do note however he
dies every attack, and going -1 every turn for this is
rather impractical, but otherwise if you have him ready,
he's not a bad choice. His main role should be swinging
for 21k alongside Romario to force 15k shield (so he's
immediately viable for Baskirk Soul-abuse, since Romario
is run to bully 10k base Vanguards), or let your Dancing
Cutlasses not suck as boosters. Don't plan your plays
around him ever, but if you can get him ready, he'll do
you some good. You damage him, and you're probably still
okay, you won't lose too much in the long run.
Tech him if you want, but he's too expensive to use at
any more than 1.
