Well, cards like Hermit Druid, which can mill your entire deck for a single mana if you avoid playing any basic lands, and the repeatable tutoring and graveyard-filling power of Survival of the Fittest are pretty busted, too
Good Against: Abzan, Jeskai (on the play more so versus Mentor), Mardu decks that arent token=heavy, Esper Dragons, basically anything with creatures that isnt doubled down on Hangarback Walker, Hordeling Outburst, or Secure the Wastes Remember when I said this deck has tricks that let it sideboard well without messing up Collected Company
One such design, namely Ghost Town, is back in vogue with MTG players this week
Masters sets in MTG are designed for Limited Draft play, which includes a bunch of rarity shifts on certain cards
The card not only is from the Gamma playtest deck, but also is the precursor to a card in the Power 9 one of the nine most-powerful cards in the game and of the highest rarity in each set that they appeared in
It also reads: "Spells you cast cost one less to cast for each card type they share with cards exiled with Cemetery Prowler." This means that if you exile a creature with Cemetery Prowler, your creatures cost one less to cast
