I'd argue it's either being mana flooded (if you've ever been the player at the table who is empty-handed and top decks lands for a couple turns in a row, you'll know what I mean) or mana screwed (see: basically every Commander Clash game from Crim's perspective)

This is an absolute beast of a card
March Of Wretched Sorrow is best played in decks playing primarily black so you have an easy way to discount it, otherwise, it's a big mana sink
