[Card]Aetherworks Marvel[/Card] [Card]Dig Through Time[/Card] [Card]Smugglers Copter[/Card] [Card]Emrakul, the Promised End[/Card] [Card]Emry, Lurker of the Loch[/Card] [Card]Felidar Guardian[/Card]/[Card]Saheeli Rai[/Card] [Card]Kethis, the Hidden Hand[/Card] [Card]Mox Amber[/Card] [Card]Narset, Parter of Veils[/Card] [Card]Nexus of Fate[/Card] [Card]Oko, Thief of Crowns[/Card] [Card]Once Upon a Time[/Card] [Card]Prized Amalgam[/Card] [Card]Teferi, Time Raveler[/Card] [Card]Treasure Cruise[/Card] This is my to do list
This is because each copy of a card varies in how well-centered it is between its black borders
Another reduces the attack power of a card by two when it's played, helping you avoid reprisal when challenging other players (every time you attack, you also take damage)
The black removal spells will take any of your Constructed decks that have black mana to another level
