Except this is not a fucking strategy game.
Not to mention that "ingenious plan" of making or imagining a game where quality of gameplay is dependent on players bad memory is - 1. completely inapplicable here, 2. completely idiotic.
Gameplay quality of any game is depend on the limits of memory and calculation. For a game with randomness, if you memorized the optimal strategies in all conditions, all there left is mere gambling.
D:OS 2's combat part is a strategy game, and it has far more elements than chess. It can certainly be done in a way that would give a good player surprises without randomness, especially if the enemies AI use some machine learning or fuzzy logic.
