Reuniclus line is from Temporal Forces, not Silver Tempest. Adventurer's Discovery is Ciphermaniac's Codebreaking.
No idea if this will work, but I am still interested in Reuniclus's Summoning Gate ability which lets you bench any pokemon you find from the top 8 cards of your deck. The idea is to stack the Nidos on your deck using Cyleene (from the discard) or Ciphermaniac (from your deck) and summoning gate them using Reuniclus. Unfortunately you can only guarantee up to 2 with either supporter so the rest is up to luck. This deck is by no means good at all but I think it would be a fun jank deck to play casually.
