Pack Selection Advice

Greetings all,

Working on putting together a Rescue Ace + Snake Eye deck. Only Rescue Ace card I am missing is x1 EMERGENCY! From the Snake Eyes side, I am missing x2 Diabellstar’s, Sinful Spoil Snake Eyes, Poplar, and Flamberge. Missing some of the extra deck, but not as much as main deck.

My question is, would I be better off going with the Rescue Ace secret pack, or going for the Diabellstar in the selection pack? Any UR pulls from chaotic showtime excluding diabellstar would be dusted. I have White Forest play sets.

Any advice is welcome!
