A short What If sketch: I get 20 seconds in the meeting to pitch a Secret Lair, and I go all in on Back to the Future.
The pitch writes itself once you start. The DeLorean lets you time travel whenever it attacks. Doc Brown lets you cast spells for free, which is heavy. And who could forget the iconic lightning bolt that sent Marty back to the future, so obviously that is a Lightning Bolt reprint waiting to happen.
Would you run a Back to the Future Secret Lair, and which card would you want most? Mine has to be that DeLorean.
