Action Card Help

[Aramax]

I just started handing out one use disposable action cards for PCs in my D&D game.
Is anybody else doing this? Do you have any good ideas for cards?(examples
Catch Breath -full round action-heal 2-6 or Mighty Blow-add 5 damage to a sucsess hit-or
Better Than That -Add 1 to any roll)
