Foils are also underpriced right now
This deck has both of those things however you have to get an awful lot of power back from your synergies as well as having them be incredibly consistent for cards like Snapping Gnarlid and Makindi Sliderunner to be better than Tarmogoyf and Scavenging Ooze
There are many permanents that provide a steady flow of card draw in black, too
With three power it should be able to crew most vehicles and will give that Vehicle a +1/+1 bonus until end of turn as well
Other prominent mechanics that incorporate (or freely enable) sacrifice include: Food, Clues, Treasures, Sagas, Unearth, Encore, Evoke, any other temporary tokens such as Faerie Artisans or Hostility, cards with Upkeep, Quests, Exploit, Casualty and now Bargain
