This is a pretty rough idea that I had, but felt like building on it a bit. It is currently untested so I'd appreciate some feedback!
So, Lycanroc does 240 damage for two energy, which sounds great, right? Well, it does 80 less damage for each energy attached to your opponent's active. In order to combat it, you use Crushing Hammer, Giovanni's Charisma, Fan of Waves, and Rugged Helmet to remove energy cards from your opponent's board. Technical Machine: Evolution gets each of your Pokemon evolved and ready, and Gutsy Pickaxe energizes. From there, just remove as many energy cards as you can! Happy Trolling!
