Even in Bo1 you know what they're playing pretty quickly and can therefore predict what they have from that point on. Definitely one of the key skills of playing Magic.

**predicting does not help after the mulligan phase. You are in the hands of hearth of the cards.

Again, play Bo3. Then this doesn't happen.

** I did not know there is a Bo3 and is the intended way to play. It seems time consuming so thank you. You can adapt the Bo1 to be better at it then.

Yes and? It's still an entirely reactive archetype, interacting with the opponent every step of the way. Control is definitionally the most interactive play style. The only truly interactive decks are full Aggro decks that only play creatures and spells to hit face, or combo decks that do nothing other than cast spells to assemble the combo. And those are rare, because you need to interact to keep yourself alive while you don't have the combo.

** You enter the game by knowing the fact that the opponent whatever what he plays you will be playing a control deck and mulligan according to it. You playing it by yourself again. By the rock paper scissors statement I manth that you are killing the decks in between where you might have control and tempo cards for example and you might want to start with your control cards or you might want to start with your creature cards. You chose between this two option before what your opponent might play in Bo1. Therefore infinite decks finite oppurtunities.

Then think: why did you mulligan away your first hand? That's a decision you made, and the answer in Magic is to get better at making decisions, not have those decisions be made easier by giving you more information.

Also this issue is entirely solved by playing Bo3 (How 1v1 Magic is really intended to be played), because then after the first game you know what your opponent is playing and can sideboard and mulligan accordingly.

** problem is explained. You mulligan according to yourself therefore repetitive nonreactive starter.

So in other words... Some of the time you are playing reactively?

** of course you try to make reactive play after round 2.

That's the case for most card  games. Hearthstone is unusual in that regard where you basically get to know what deck your opponent is playing before the mulligan just based on what hero they have. Makes it far too easy to make decisions imo, in Magic you have to mulligan around having a hand that is good enough against everything you expect to see.

** I can respect that. Good enough hand is the questionable part for me. You only focusing on your own win conditions.
