Name the beatdown before turn three

In a given pairing, one deck needs to win the race and the other needs to not die. If both players try to be the control, the actual beatdown deck wins by accident. If both try to be the beatdown, the faster deck wins and the other looks confused.

Name the role before you spend your third land drop.

You are the beatdown if your cards are worse in a long game — smaller threats, less card advantage, a clock that only works if it starts now. You are the control if you can go over the top given time: bigger spells, more land, sweepers, a late-game that the opponent cannot match.

The test is ugly and useful: if the game goes to turn nine, who is happy? If it is not you, you needed to attack earlier. If it is you, you needed to not die for a resource you have not spent yet.

This changes which cards are good. A removal spell is a tempo play when you are the beatdown (clear a blocker, keep the clock). It is a two-for-one setup when you are the control (wait, double up, then take the turn off). Playing a control removal sequence with a beatdown deck is how fair midrange lists lose to worse decks.

Sideboarding follows the same sentence. You board in more cheap interaction when you need to not die. You board in more redundant threats when you need to present a clock through their answers. If you cannot say which of those you are doing, you do not have a sideboard plan. You have fifteen cards you like.
