pokemon sparkling surge booster pack Scarlet & Violet - Surging Sparks it lights up the shoreline Pokemon Scarlet & Violet Surging

The synergy in this deck is off the charts

You must perform the action

Maybe turn into a pidgeot ex and arven deck with new tech attackers

You don't want to prevent any damage dealt to yourself, since Roaring Moon ex puts itself on that magical "30" for the Emergency Jelly to trigger

No, but collector boosters are your best bet , since their appearance rate is the best, and foil Special Guests are reserved for collector boosters

The Core backside of Matzalantli, the Great Door seems more reliably powerful than the Gaea's Cradle backside that is Itlimoc, Cradle of the Sun unless you are in elfball, but its harder to flip and the front side doesnt do quite enough
