Today’s “Card of the Day” features a forerunner for Descendant!
From G Booster Pack Vol. 9: Divine Dragon Caper (Release Date: December 16, 2016) we got:
Eradicator, Ambitious Dragoon
Grade 0 | Normal Unit
Narukami | Human | Dragon Empire
[AUTO](RC)[Generation Break 1]:When your vanguard with “Descendant” in its card name’s attack hits a vanguard, you may return this unit to your hand.
“Youths have big dreams.”
[Editor’s note: I mean, some additional shield is fine to dream about, I guess.]
