I imagine a less impactful bonus could be given in the form of a free scry on endstep

scry comes too late for it to have an impact on turn 1, but can be used to dig for something without giving card advantage

plus mindgames, Player 2 sees that P1 scry and topped, does that mean they found their combo piece etc.

but any change to game rules will create decks that are made to exploit it. As there are decks now that excel on the play or draw
