Wight of the Reliquary is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.

Official card text

Vigilance This creature gets +1/+1 for each creature card in your graveyard. , Sacrifice another creature: Search your library for a land card, put it onto the battlefield tapped, then shuffle.

Complete guide

Wight of the Reliquary is a powerful new addition to Golgari decks, serving as both a scaling threat and a potent utility engine. By feeding on your fallen creatures, it grows in size while allowing you to tutor for any land in your deck.

A Growing Menace

The first ability of Wight of the Reliquary is a static effect that constantly checks your graveyard. For every creature card residing there, the Wight receives +1/+1. Because it has Vigilance, it can attack without tapping, leaving it ready to use its activated ability during your post-combat main phase or on your opponent's turn.

Step-by-Step Resolution

To activate the Wight's ability, you must pay the cost: tap the Wight and sacrifice another creature you control. Once the ability is on the stack, it cannot be countered by simply killing the Wight. When the ability resolves, you search your library for any land card—not just a basic land—and put it onto the battlefield tapped. Finally, you must shuffle your library.

Strategic Timing

Since the land enters the battlefield tapped, this ability is often best used at the end of your opponent's turn. This ensures the land is ready to be untapped during your next untap step. Additionally, remember that the sacrifice is a cost; if an opponent tries to destroy one of your small creatures, you can respond by sacrificing it to the Wight to get value before it dies anyway.

Common Mistakes

A common error is trying to sacrifice Wight of the Reliquary to its own ability. The text specifically states 'sacrifice another creature,' meaning the Wight cannot be the fodder. Also, keep in mind that the +1/+1 bonus changes instantly as creature cards enter or leave your graveyard; if a spell exiles your graveyard, the Wight's power and toughness will drop immediately.

Interaction examples

Early Game Acceleration

Llanowar Elves

If you have Llanowar Elves on the battlefield, you can tap the Elves for mana early in the turn. Later, you can tap Wight of the Reliquary and sacrifice the Llanowar Elves. This puts a creature card in your graveyard, giving the Wight +1/+1, and allows you to search for a powerful utility land or a needed color source.

Fixing Your Mana

Birds of Paradise

If you control Birds of Paradise but desperately need a specific land like a tri-land or a utility land, you can sacrifice the Birds to the Wight. The Birds of Paradise will now contribute a +1/+1 bonus to the Wight from the graveyard, and you will have tutored a specific land directly to the battlefield.
