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)
However, during the late game, you can reuse your Expert Belts and Pokmon Rescues to claw your way back into the game
This set is an expansive one, with 83 Team Rocket's Pokmon cards, 17 EX cards, 23 Illustration Rares, 11 Special Illustration Rares, and 6 Hyper Rare gold-etched cards
In a four player Commander game, Smothering Tithe can easily bag you five or six treasures per turn, and if the other players let the card sit on the table unchallenged, it can easily catapult you to victory
Lucario ex costs 500 Pack Points to craft
So I hope that day comes again soon
