If it's on the 2, it moves to the 1
Ulvenwald Mysteries can be part of a dedicated Clue plan, giving us a free 1/1 token for every Clue cracked, in addition to providing us with a plethora of Clues over time (since many of our creatures are going to give us Clues unless they die, and if they die, then the Ulvenwald Mysteries will give us Clues as to what happened)
It includes cards like Dragon Tempest , Terror of the Peaks , and Lathliss, Dragon Queen , which synergize with Vrondiss and other dragons to create a devastating board presence
These arent even the most expensive
Persian, Zorua, and Pecharunt ex are all really strong picks from that set, and Misdreavus and Banette from Ascended Heroes fit perfectly alongside them
