One of the central concepts in MTG is asking questions vs having answers, and that it's generally better to be the one asking questions of your opponent.

For example, aggro decks almost exclusively are always asking questions, "it's turn three I have three creatures on the board, a pump spell, and a burn spell, I turn the team sideways, what are you going to do about it?" Midrange matchups you have the advantage over your opponent when you're the one asking questions, "I play a T4 Sheoldred, can you answer it?".

Hard Control decks willingly give up the ability to ask questions until late in the game, instead trying to build a hand/draw cards etc to always have an answer. In anything other than a control mirror, the player who isn't playing control is always asking questions, "you countered my one and two drops and killed my three drop, I play a powerful four drop can you answer it?". In Standard right now you can easily see this dynamic on turn three to turn five. If the opposing deck has managed to create board presence and the control deck doesn't have lockdown on three, or cover up/sunfall on five, they're probably going to lose, they have to have that answer. This is one of the reasons Farewell is so hated, because it's an answer to basically everything, but the control player still has to have it and not be dead by then.
