Had the same, won 3 times with a new deck and didn't get it in my standard or custom decks. After I won 3 times with my initial, different deck, it seems to be bugged.

Why this bug only showed up now is a mystery, but now I literally have no way to gain access to 2-color starter decks that have been removed from my collection.

In addition to the 3 decks mentioned by Peppersauce#33544, I'm also missing the GR deck and I'm quite unhappy losing that deck from my Starter Decks if the way to get it back doesn't work.

The exact same thing happened to me, looks like 3 of the starter decks (BW/BR/UR) got updated with new cards I don't have, after noticing that I started playing that new mode to get the cards I'm missing before I hit them as ICRs or in packs. (already happened once with Static Net and there's 3 copies of it in the BW deck)

After 3 wins I received 2 rare ICRs and a new card style but not the 5-6 cards I'm missing to complete the BW deck. As a F2P user it's not ideal since ICRs are a neat way to add to my collection but now there's the risk I "waste" a bunch of them on cards I should receive through the updated starter decks anyway. That is, unless I'm misinterpreting the message in the event.

Despite winning 3 games in Starter Deck Duel mode with the Black and White deck it did not show up in my Starter Decks.

I am having this issue as well. It is trying to get me to use my wild cards to complete the deck. I’ve played this deck before with no issues, why would I use my wild cards to complete it now? It’s a starter deck, it should be complete to begin with.

Storm of Blades is unplayable because of two cards are missing.
