Enchant Wall
Enchanted Wall can attack as though it didn't have defender.

You gain life equal to the damage dealt to you this turn. Simulacrum deals damage to target creature you control equal to the damage dealt to you this turn.

This creature enters with X +1/+1 counters on it.
For each 1 damage that would be dealt to this creature, if it has a +1/+1 counter on it, remove a +1/+1 counter from it and prevent that 1 damage.
: Prevent the next 1 damage that would be dealt to this creature this turn.
: Put a +1/+1 counter on this creature. Activate only during your upkeep.

Black creatures get +1/+1.

First strike (This creature deals combat damage before creatures without first strike.)
Protection from black (This creature can't be blocked, targeted, dealt damage, or enchanted by anything black.)

Destroy target artifact.

At the beginning of each player's draw step, if this artifact is untapped, that player draws an additional card.

Spend only black mana on X.
Drain Life deals X damage to any target. You gain life equal to the damage dealt, but not more life than the player's life total before the damage was dealt, the planeswalker's loyalty before the damage was dealt, or the creature's toughness.

Whenever one or more creatures you control attack, each defending player divides all creatures without flying they control into a "left" pile and a "right" pile. Then, for each attacking creature you control, choose "left" or "right." That creature can't be blocked this combat except by creatures with flying and creatures in a pile with the chosen label.

At the beginning of each player's upkeep, this enchantment deals X damage to that player, where X is the number of untapped lands they controlled at the beginning of this turn.

Target player draws X cards.

: You may choose a creature card in your hand whose mana cost could be paid by some amount of, or all of, the mana you spent on . If you do, you may cast that card face down as a 2/2 creature spell without paying its mana cost. If the creature that spell becomes as it resolves has not been turned face up and would assign or deal damage, be dealt damage, or become tapped, instead it's turned face up and assigns or deals damage, is dealt damage, or becomes tapped. Activate only as a sorcery.

Whenever a Forest an opponent controls becomes tapped, you gain 1 life.
