I discuss Aysen Crusader here because errata changes the Homelands text from Heroes to Soldiers and Warriors. For the hero creature type, look to cards from Final Fantasy and newer
a football star offered $150k, which was soon bumped to $500k, then $1 million, before rising to $2 million dollars and a paella
(11/3/2023) If you cast a card "without paying its mana cost," you can't choose to cast it for any alternative costs
There are a number of ways to close the game while keeping with your life gain theme
(As a reminder, spending a gold on a 0-cost cards Draw 2 ability does not trigger ally abilities.) So, when you take into consideration the fact that I probably wont cast this more than a few times a game, and the fact that it doesnt impact the board at all, I am not convinced that this is a consistently worthwhile Dark Draft card
Maybe youd rather include a ramp spell or a card draw effect
