Arms of Hadar / Krark-Clan Shaman : very strong options in a metagame full of monocolored aggro decks
The target opponent doesn't choose whether to sacrifice a creature or not, although they do choose which creature they control to sacrifice
You can build decks from cards you actually own, scan cards with your phone camera, and track set completion
but Im concerned about it in this deck, as it has a fair amount of tension with Ashiok
For most Magic: The Gathering decks, a card in the graveyard is as good as gone
Don't get me wrong, I understand that those numbers have nothing to do with the token ability, which is just kind of gravy on a mediocre card draw trigger, but that trigger is decidedly mediocre, even if you're in the dedicated lifegain deck
