It can steal a combo piece

The Ruinous PowersUniverses Beyond: Warhammer 40,000Commander Deck set includes 1 ready-to-play Blue-Black-Red deck of 100Magic: The Gatheringcards (2 legendary traditional foil cards, 98 nonfoil cards), 1 foil-etched Display Commander (a thick cardstock copy of the commander card with foil etched into the cards border and art), 10 double-sided tokens, 1 deck box (can hold 100 sleeved cards), 1 life tracker, 1 strategy insert, and 1 reference card

In formats where Shocklands and Fetchlands are common, this can easily put someone down to critical levels

For that reason, it is a slow or late game combo
