is landfall an activated ability
is landfall an activated ability
No. Activated abilities are always written in the form "Cost: Effect". Landfall is a triggered ability (except on instants and sorceries, where it's a replacement effect).

No, it isn't activated. At all. Ever.

For Bloodghast's landfall ability, can I choose to leave him in the graveyard if I put a land into play. Like if I have a Crypt of Agadeem in play and I want to build it up to play a bigger card? Bloodghast's ability says that I "may" return him to play...
