Constellation -- Whenever Agent of Erebos or another enchantment enters the battlefield under your control, exile target player's graveyard.

Reveal the top five cards of your library. You may put a creature card and/or an enchantment card from among them into your hand. Put the rest into your graveyard.

Enchant creature card in a graveyard

When Dance of the Dead enters the battlefield, if it's on the battlefield, it loses "enchant creature card in a graveyard" and gains "enchant creature put onto the battlefield with Dance of the Dead." Put enchanted creature card onto the battlefield tapped under your control and attach Dance of the Dead to it. When Dance of the Dead leaves the battlefield, that creature's controller sacrifices it.

Enchanted creature gets +1/+1 and doesn't untap during its controller's untap step.

At the beginning of the upkeep of enchanted creature's controller, that player may pay {1}{B}. If the player does, untap that creature.

When Deadbridge Chant enters the battlefield, mill ten cards.

At the beginning of your upkeep, choose a card at random in your graveyard. If it's a creature card, put it onto the battlefield. Otherwise, put it into your hand.

Whenever one or more creatures attack, you may have target attacking creature gain double strike until end of turn.

When Golgari Thug dies, put target creature card from your graveyard on top of your library.

Dredge 4 (If you would draw a card, you may mill four cards instead. If you do, return this card from your graveyard to your hand.)

Flying, first strike, haste

Constellation -- Whenever Harvestguard Alseids or another enchantment enters the battlefield under your control, prevent all damage that would be dealt to target creature this turn.

Once during each of your turns, you may cast a creature spell from your graveyard.

Bestow {3}{G} (If you cast this card for its bestow cost, it's an Aura spell with enchant creature. It becomes a creature again if it's not attached to a creature.)

Reach

Enchanted creature gets +2/+2 and has reach.

Creatures you control have trample. (A creature with trample can deal excess combat damage to the player or planeswalker it's attacking.)

Flying

Whenever Silent Sentinel attacks, you may return target enchantment card from your graveyard to the battlefield.
