Maybeboard

• Blightstep Pathway - maybe I would replace two Dragonskull Summits with two copies of this card. Very often two - three copies of Dragonskull Summit came to my starting hand.

• Liliana's Defeat - this is an interesting option against monoblack and rakdos decks. After the uro ban in the meta, there should be less control decks and more aggression. Therefore, I would plan to replace one copy of Angrat with this card.

• Chandra's Defeat - this is an interesting option against monored and gruul decks. After the uro ban in the meta, there should be less control decks and more aggression. Therefore, I would plan to replace one copy of Angrat with this card.

• Gifted Aetherborn - I play this card instead of Aethersphere Harvester because I do not currently have enough jokers on Aethersphere Harvester. And this card is still a good answer to aggressive decks.

• Valki, God of Lies - I didn't really like this card against Sultai/4-С Midrange. True, I lost a couple of times to this card from the enemy side, when it expelled Immersturm Predator from my hand. I'm still not happy with this card, but I have to admit that it has huge potential.

• Agadeem's Awakening - it might be worth considering adding this card to the base of the deck. Our deck very often puts creatures in tempo. They often die from enemy black spells. And when I go 5-6 mana the graveyard is filled with creatures. And this card will help bring these creatures back. Unless you are playing against aggressive decks, since the game against them is already over by the fifth turn.
