Well, there are options such as "Run and hide," but those generally don't let you win. The number one way is to destroy Toon Kingdom, then beat over it. If you're lucky, they don't have Toon Kingdom out first-turn, which makes countering this MUCH easier. Against 3SDers using this, Lava Golem/Paracide can be effective.
Sounds good. So basically just hope they don't get a hold of toon kingdom early on and just 🔥 that barrel dragon by any means possible, its just much harder to do so now.
