It's definitely a big hit to 🔥 burn decks. But since it still allows for a deck with this skill to have Lava Golem, it's sadly not the end. They can fill the 4 insect requirement with Man-Eating Bug, Krawler Spine, 4-Star Ladybug and Naturia Dragonfly for that 🔥 style of play.
It still means they have to get rid some of the stall monsters to put in those Insects, otherwise they'll face consistency issue.
And honestly, I'll take having to deal with Man-Eating Bug or 4-Starred Ladybug than dealing with Fortress Warrior + Obnoxious Celtic Guard.
They also can't run 2 Econ 3 Swordswoman anymore now that Swordswoman is semi-limited as well.
I'm expecting burn decks to still be a thing, and if they continue to be fairly common, I'd imagine Semi'd Lava Golem will happen eventually to finally 🔥 the thing. (Really wish that happened along with Swords Woman, but eh.)
In addition to semi-limiting Lava Golem, they would need to semi limit a few of the other stall cards as well, if they truly want to 🔥 Lava Golem decks.
Realistically, Lava Golem + Swords Woman along with the Parasite Infestation nerf would be all that's necessary to make burn kinda not worth it anymore. The backrow and other monsters typically aren't the win conditions of the deck, it's usually the damage from Golem and Swords Woman.
That's right, it's still a big hit... all that backrow 🔥 isn't a guaranteed win without Swordswoman... I hope those horrid decks become less common now. Desperado screws them hard as well.
"They haven't stopped to think that"... true of most of them. I've seen a parasite burn player Floodgate that monarch frog... those guys are complete idiots.
