If you pay the dash cost to cast a creature spell, that card will be returned to its owner's hand only if it's still on the battlefield when its triggered ability resolves
I cant emphasize enough how powerful taking game actions, like drawing cards, by spending zero mana can be so I think Sanguine Spy might be secretly pretty good
Heres Miharas mana curve: The numbers are sort of misleading here because Whip of Erebos isnt truly a 4-drop (youd rather lead with a Polukranos, World Eater or Eidolon of Blossoms on 4 mana)
This one's technically an artifact, but it's a new artifact land
As well as casting artifacts, Powerstone mana can be used to pay for activated abilities on any kind of card (such as equip or unearth ), or pay for taxes like cumulative upkeep, ward, and commander tax
