I like the second strategy quite well, since 50 damage for two energy cards is quite good, but if you pair this card with a card like Snorlax that can attack while asleep, you could keep this card on the bench, put the defending Pokemon to sleep every turn, then still attack
Its not caring about getting your hands dirty, because theres literally no other way to get the job done
Agathas Soul Cauldron Targeted graveyard removal every turn for an initial cost of two is already extremely useful, and thats just the start of what Agatha can cook up with this cauldron
It's even more difficult when Pendulum Monsters are thrown in during the following Arc-V campaign
Either way, once you stick Destruction Dragon on the field, itll bring about the destruction of your opponent
Then shuffle your deck
