The second reason is that Old School players actually care about Preacher to steal creatures from their opponents and sacrifice them to stuff like Diamond Valley or Ashnods Altar
(It's an artifact with "2, T, Sacrifice this artifact: You gain 3 life.") +1: Target artifact or creature loses all abilities and becomes a green Elk creature with base power and toughness 3/3
Is Fork part of any infinite combos
that creatures gone for good
(Until there are enough options for a high-density of solid sacrifice outlets in Temur colors, I wouldnt go all in on that plan, but the one-off is a nice option that synergizes with the rest of the deck.) There are a lot of creatures with great abilities for +1/+1 counters, and we also just want back-up options in case casting our commander becomes difficult
My recommendation: keep eBay in your back pocket for selling cards, but also keep an eye out for an occasional deal on a card youve been searching for
