I mostly play an archespore fog deck and I've been seeing a lot of my opponents tech in Mahakam Marauder to completely shut down a hazard on the row. Normally, clearing the hazard would be the better play but because my deck also focuses on using archespores as an engine this Mahakam Marauder is a double shut-down to my deck, growing more powerful every time the archespore hits it.
I'm not salty at all, rather I'm impressed with the design of Gwent to have such a yin-yang moment where I encounter the exact perfect counter to my deck. Throwing a question out to all you Gwenters (Gwenties?) : What card was a 'perfect counter' to your decks?
