MTG Mono Black Midrange Deck by Keldz

Whenever you cast a colorless spell, create a 0/1 colorless Eldrazi Spawn creature token with "Sacrifice this token: Add {C}." Whenever another colorless creature you control enters, this creature deals 1 damage to each opponent.

({C} represents colorless mana.) When this creature enters, target opponent reveals their hand. You choose a nonland card from it and exile that card. When this creature leaves the battlefield, target opponent draws a card.

You may reveal this card from your opening hand. If you do, at the beginning of your first upkeep, look at the top four cards of your library. You may put one of those cards back on top of your library. Exile the rest. When you cast this spell, exile target permanent that's one or more colors.

First strike, vigilance Menace, trample Reach, lifelink Ward—Pay 7 life.

When you cast this spell, exile two target permanents. Indestructible Whenever Ulamog attacks, defending player exiles the top twenty cards of their library.

This artifact enters with X charge counters on it. Whenever a player casts a spell with mana value equal to the number of charge counters on this artifact, counter that spell.

{T}: Add {C}. {1}, {T}, Sacrifice this artifact: Draw a card.

({B/P} can be paid with either {B} or 2 life.) Target creature gets -5/-5 until end of turn.

Put that card into your hand.
