Foreverwatcher

Each turn, at the start of your upkeep, if Foreverwatcher is the only artifact you control and you have 9 or more artifact cards in your graveyard, you gain 2 life and you draw a card.
When Foreverwatcher dies, exile all artifact cards on the battlefield and in all graveyards.
Landfall -- Whenever a land enters the battlefield under your control, sacrifice an artifact.
