get rid of water hazard, that card is only useful if you draw it first or second turn, based on your deck i would replace it with big wave small wave, and to be honest you don't need riryoku with this deck... when daedalus comes out there's only 4-5 cards that can counter it, you will actually never have the chance to use riryoku, i would replace it with some trap cards
