Can you get Black Luster Soldier in any booster packs?

Answer 1

Yes, you can find it as a regular rare, DPYG-EN017, in the relatively recent Duelist Pack Yugi.

Lets not forget, we're not talking about "Black Luster Soldier - Envoy of the Beginning", we are talking about "Black Luster Soldier" (SYE-024). "Black Luster Soldier - Envoy of the Beginning" is in Invasion of Chaos and, more recently, Dark Revelation 2. But the question is where to get Black Luster Soldier, other than the Yugi Evolution deck.

As well as the DPYG and SYE versions, there is a parallel rare form available in one of the Mattel toy packs, series 3.
