I think perhaps you’d enjoy a weird homebrew nonsense thing I made a while back. Essentially I turned maneuvers into a deck building game. The warrior got a series of maneuver cards, at the start of combat you shuffle and draw a hand. Once used a maneuver could not be used again. At the beginning of each of your turns draw an additional card.
At any time you can take a “reposition” action, where you shuffled up all your cards in the deck, hand, and used piles and drew a new hand.
It was incredibly fun the times I tried it. But it’s a bit much for a 5e homebrew.
