Got a story of a budget card beating the pants off of a pricey card
Pro Tours are meant to showcase new cards, and Wizards was concerned that players wouldn't include any Homelands cards in their decks
While i take your point about sideboard specific cards i would class the blasts and disenchant very differently - one is a occasion maindeck card with very wide sideboarding potential while the other is very obviously a sideboard only colour hoser
The fact that this combo is pulled off by the interaction between a lotus artifact (which are very prominent in East Asian and Japanese Buddhist art and symbology), a moonfolk from Kamigawa (a plane directly based on Japan), and the legendary creature that represents the patron spirit of all moonfolk
This includes spells that target a single creature
Meanwhile, stax pieces like Narset, Parter of Veils, and Alms Collector turn this into a net-positive card
