Ok, wow. Something seemed really off about the card drops and this fits perfectly. I've opened 82 chests total, I think, but my new cards in the last 20-30 had slowed to a trickle.
I can confirm Shadow Chain, but that's it. My missing cards are the non-yellow ones you listed with only a few extra... Deck 4 items making up half of that list, for whatever reason.
I noticed this pattern too. Snaring Net and Reveler are new to me and now I have 3 of one and 7 of the other. Other notable new appearances are Steel Ibis Lamellar (common, 5) and Brooch of Shielding (legendary, 4)(!!!).
Venomous Darts +2 deserve a mention in that -- despite being a rare-level card -- they drop almost as often as basic common allies, i.e. every few chests. I think I'm up to 12.
