Combos Utilizing Rising-Waters

When your opponent plays a land, all his lands tap and only one may be untapped at his uptap phase! Just make sure you don't play a land!

You return three islands to your hand.Play two lands and then you countered and have two mana free!

during you turn, return rising waters to your hand. then leave enough mana to play it at the end of turn. also leave 1 land untaped. during their turn, tap their land and they cant play anything.

counter opponents spell while attacking them with creatures . eye of ramos gives you mana and voltaic key untaps your eyes of ramos. Then use creatures like indentured djinn or spinedrift drake!!!

tap your opponent out, drr

play tahiawah ,then rising waters , next turn play armmageddon::: this work best against counter decks

At the end of opponents turn return waters to your hand and play it after untap step!

Tap out, play whatever you want, then untap all of your lands with turnabout!

Play Cowardice and Prodigal Sorcerer. When you put Rising Waters into play the opponent will have a hard time getting the mana to put their creatures back into play. When there is no creatures for the Cowardice+Prodigal Sorcerer combo just tap Prodigal Sorcerer to do 1 damage to opponent. You will slowly win against a creature deck.

Your opponent never untaps. I'm surprised no idiot here thought of that.
