There is not much that can block a big Deaths Shadow, however, many of the common removal spells of the format can take care of it, until Lurrus Deaths Shadow and the namesake deck are emblematic for how Magic is played today, interrupt your opponent, play a cheap strong threat and counter whatever your opponent tries to play against you
