What Turbine Wanted

Discard any number of cards. Search your library for up to that many basic land cards, reveal them, put them into your hand, then shuffle.

Reveal your hand: If you have seven or more land cards in your hand, flip Sasaya.

Whenever a land you control is tapped for mana, add an additional one mana of any type that land produced for each other land you control with the same name as it.
