Skeletons, Vampires, and Zombies you control get +1/+1. At the beginning of your end step, if a creature died this turn, you may pay {1}. If you do, create a 1/1 black Skeleton creature token.

{T}: Add {G}. Put a -1/-1 counter on this creature: Untap this creature.

Constellation — Whenever this creature or another enchantment you control enters, draw a card.

If a creature an opponent controls would die, exile it instead. At the beginning of your upkeep, put all creature cards exiled with Gisa 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.)

{T}: Add X mana of any one color, where X is the number of enchantments you control.

If an effect would create one or more tokens under your control, it creates twice that many of those tokens instead.

At the beginning of combat on your turn, mill a card. When you do, if there are four or more creature cards in your graveyard, put a +1/+1 counter on target creature you control and it gains deathtouch until end of turn. (To mill a card, put the top card of your library into your graveyard.)

Each Skeleton you control has trample, attacks each combat if able, and gets +X/+0, where X is the number of other Skeletons you control. At the beginning of your end step, create a tapped 1/1 black Skeleton creature token. If a creature died this turn, create two of those tokens instead.

As an additional cost to cast this spell, sacrifice a creature. Search your library for a creature card, reveal it, put it into your hand, then shuffle.
