Blind? Sure. There’s no guarantees that they have a sphere at all and certainly not on turn 1 if inspector didn’t resolve. You are missing the forest for the trees. The forest is their clock, which is dangerously fast with mr. inspector. Without it one can trust an oath deck to get to 3 lands by the time it matters. With it in play all bets are off and insane speed is no a possibility. Remember that sphere hampers their speed as well with no inspector in play and their ability to lethal you. I have the same problem with players who don’t force Lotus vs blue only to get blown out by multiple threats the following turn. Again, do not conflate my comments with this particular scenario where the shop player kinda had it all and also topdecked like a champ. Understand that I’m playin the numbers and making the play that wins me the majority of games.
