To determine the total cost of a spell, start with the mana cost or alternative cost (such as a flashback cost) you're paying, add any cost increases, then apply any cost reductions. The mana value of the spell is determined only by its mana cost, no matter what the total cost to cast the spell was.

If an effect allows you to cast Memory Deluge without paying its mana cost, X will be 0. Memory Deluge will resolve, but you won't do anything.

If an effect requires you to pay some amount of mana to prevent Memory Deluge from being countered, as Flip the Switch does, that mana wasn't spent to cast Memory Deluge and will not be taken into account.

If a card with flashback is put into your graveyard during your turn, you can cast it if it's legal to do so before any other player can take any actions.
