Lightning Bolt paired with a massive trample creature is horribly hard to deal with
Just sacrifice a trivial merfolk token after each swing and you can easily complete a victory lap of the table (or set up a different win con) over several consecutive turns
Notably, Korvold will benefit from any Magic card type being sacrificed, not just Treasures, so the deck can also use sacrifice-related cards like Sakura-Tribe Elder
I asked it to draw the art in the style of Rebecca Guay, my favorite MTG artist
In general, Planeswalkers and other noncreature threats tend to be good sideboard cards against slow decks
