Prototype MTG Mechanic The Brothers' War features prototype cards, which have a mechanic that represents an artificer's work in different stages of development

You can create pretty consistent scenarios where you play a room card and unlock the other door: Victor, Valgavoth's Seneschal lets you surveil 2 while your opponents discard a card

Cards like Tourach, Dread Cantor or Dauthi Voidwalker can substitute Shadow really well giving more midrange quality to the shells while Ragavan and DRC are the turn 1 tempo openers for the decks

Repeatable sacrificing is pretty rare, and can force a sort of soft lock on people, so I think this is definitely potentially playable, also in angel tribal its pretty good

By default, these goats lack any Power and have very low Toughness, making them questionably useful in a fight
