Dreamblade Quest

Whenever a creature you control attacks alone, put a quest counter on Dreamblade Quest.
Remove three quest counters from Dreamblade Quest and sacrifice it: Create a colorless legendary Equipment artifact token named Dreamblade. It has hexproof, "Equipped creature has hexproof and 'Whenever this creature attacks alone, you draw X cards and gain X life where X is this creature's power,'" and equip {0}.
