Strength of Night both normal boost and kicker boost share same legacy card.

Which card did behave improperly ?
Strength of Night

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink 2016/08/27: Eldritch Moon v2, duel

What exactly should be the correct behavior/interaction ?
Strength of Night normal boost and kicker boost have different legacy cards.

Are any other cards possibly affected by this bug ?
-

Why is this a bug? Isn't it preferable to have fewer legacy cards?

It's a bug because it's currently the worst of both worlds: your Zombies get two effect cards added, and each has the text of both effects. It should be a single effect card per creature, preferably only mentioning the Zombie part on the effects added to Zombies.
