Did you agree with my placements, or do you have some suggestions
FLUSTERSTORM One of the very first cards printed into the game as a Commander precon deck exclusive, Flusterstorm immediately carved out a home in Legacy and other eternal formats
So shes a steal at less than $1
Sideboarding The key to understanding how to sideboard with Rainbow Dredge is very much aligned with how the deck operates
Perhaps going heavier Blue would have been better, as it seems to be the only color that allows you to draw cards reliably (along with Black)
While the spike in price is also due to scalping (the practice of buying large quantities of popular or limited-edition products at retail price to reduce supply and increase demand), or the number of new people who only want to collect, if the card gets banned as a result of the skewed metagame, that value will likely drop, pissing off more than one dedicated collector
