If a creature an opponent controls would die, exile it instead. At the beginning of your upkeep, put all creature cards exiled with Gisa, Glorious Resurrector onto the battlefield under your control. They gain decayed. (A creature with decayed can't block. When it attacks, sacrifice it at end of combat.)

Kicker {B} (You may pay an additional {B} as you cast this spell.) When Benalish Sleeper enters the battlefield, if it was kicked, each player sacrifices a creature.

Flying When Eyetwitch dies, learn. (You may reveal a Lesson card you own from outside the game and put it into your hand, or discard a card to draw a card.)

Flying When Gravelighter enters the battlefield, draw a card if a creature died this turn. Otherwise, each player sacrifices a creature.

Whenever one or more other creatures die, draw a card. This ability triggers only once each turn.

As an additional cost to cast this spell, sacrifice an artifact or creature. Draw two cards and create a Treasure token. (It's an artifact with "{T}, Sacrifice this artifact: Add one mana of any color.")

({T}: Add {W} or {B}.) As Godless Shrine enters the battlefield, you may pay 2 life. If you don't, it enters the battlefield tapped.

If you control two or more other lands, Hive of the Eye Tyrant enters the battlefield tapped. {T}: Add {B}. {3}{B}: Until end of turn, Hive of the Eye Tyrant becomes a 3/3 black Beholder creature with menace and "Whenever this creature attacks, exile target card from defending player's graveyard." It's still a land.

Isolated Chapel enters the battlefield tapped unless you control a Plains or a Swamp. {T}: Add {W} or {B}.

({T}: Add {W}.)

Shattered Sanctum enters the battlefield tapped unless you control two or more other lands. {T}: Add {W} or {B}.

Cleave {4}{W}{B} (You may cast this spell for its cleave cost. If you do, remove the words in square brackets.) Destroy all creatures [with mana value 2 or less].
