To be fair, you have to have a very high IQ to understand Krark-Clan Ironworks combo. The decision tree is extremely complex, and without a solid grasp of mana abilities most of the plays will go over a typical viewer's head. There's also Matt Nass's nihilistic outlook, which is deftly woven into his video - his personal philosophy draws heavily from Mike Flores literature, for instance. The KCI pilots understand this stuff; they have the intellectual capacity to truly appreciate the depths of these interactions, to realise that they're not just game-winning - they say something deep about LIFE. As a consequence people who dislike KCI truly ARE idiots- of course they wouldn't appreciate, for instance, the depth in every KCI pilot's catchphrase "return KCI with the Myr Retriever death trigger, return Pyrite Spellbomb with the Scrap Trawler trigger for Myr Retriever, Myr Retriever with the Scrap Trawler trigger for KCI,  infinite mana to replay all these and GG." which itself is a cryptic reference to the Grecian mythology of Sisyphus. I'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as a four-mana engine combo's grand symphony unfolds itself on their computer screens. What fools.. how I pity them.
