mtg vivien cards War of the Spark Rare Vivien, Champion of the Wilds #180 Casting Cost Card Type Vivien, 14 cards | Magic:

This means your deck is naturally limited to what Avatar: The Last Airbender provides

Similarly, cards like Teferis Protection (34,379 decks on EDHREC) and Heroic Intervention (54,217 decks) turn most advantages you might gain into more advantage for them

This turns a board full of Pest and Bat tokens into a massive mana discount for your removal and finishers

I wouldnt play this tutor in every black deck, but Id certainly consider it if I had a bomb like Liliana, Dreadhorde General

at the very least, dont go above three

That means there was going to be some crazy foreshortening, which can be really hard when you are just trying to paint it from imagination
