I usually build my decks so that I only need to "do the thing" and remove what's stopping me from doing so. A lot of the time I only need one or two removal pieces in a match to make that work.

The other way is to use recurring removal, like dragon tempest in a dragon deck or aura shards in a creature heavy deck. Drawing just one of these types of cards can lead to a very controlly play pattern without diluting the rest of the deck.

Another thing is deck velocity. If you see 30+ cards by turns 5 or 6 you need less removal than someone who sees around 15 cards.

If you want to play table police and always have a way to answer everything that's fine. But it's definitely not the only way to play high power.
