Bloodtithe Harvester (Retro Frame) [Innistrad Remastered]

When Bloodtithe Harvester enters, create a Blood token. (It's an artifact with "1, T, Discard a card, Sacrifice this artifact: Draw a card.")
T, Sacrifice Bloodtithe Harvester: Target creature gets -X/-X until end of turn, where X is twice the number of Blood tokens you control. Activate only as a sorcery.
