virtue cards mtg Teval, Arbiter of from Tarkir: Dragonstorm Spoiler Embereth Blaze deals 2 damage to any target MTG Wilds of Eldraine Virtue

I like to think of it like a handy notebook for spontaneous card ideas

You can use it against greedy self-mill decks that are looking to reanimate a bunch of creatures and its even efficient enough to see play in higher power tables where cards such as Underworld Breach are mainstays

On a smaller scale, Minas Tirith Garrison and Syr Elenora, the Discerning both add to your hand and get powered up from it

Even a card like Greater Good can be turned into a self-mill piece so long you have enough creatures to sacrifice and cards to discard, though it might not have been on your radar in regards to self-milling before
