Necrolancer

Necrolancer is an archetype of DARK Zombie-Type monsters released by JrH154 in early May, 2016. The archetype is extensively combo-based, and makes heavy use of both Excavation and Banish manipulation.

The Main Deck Necrolancer monsters are supported by Xyz Monsters and Spell/Trap Cards of the same name.

Summary
The archetype universally revolves around excavating and banishing specific monsters from the top of the Deck, and then Special Summoning those banished monsters in order to gain effects. Said effects are varied, but focus largely on maintaining hand and field advantage by adding cards to the hand and summoning monsters, for the former and latter respectively.

The archetype's monsters trade raw power in favor of consistency. They lack prominent removal effects and have relatively low ATK and DEF. However, they make up for it with the ability to continually maintain hand and field presence. To this extent, the archetype's power comes primarily from its Spell & Trap Cards, which gain additional advantage in response to various conditions that the archetype's monsters fulfill.

Main Deck
The archetype's Main Deck monsters are made up primarily of Level 3 and Level 2 monsters. These monsters' effects are all structured the same: In addition to these, the archetype also has a Level 7 monster and a Level 8 monster that bolster the archetype's speed by activating effects during your opponent's turn.
 * They have a primary effect that excavates a certain number of cards from the top of the Deck. Any excavated "Necrolancer" cards are banished, while any other cards are simply sent to the Graveyard.
 * They also have 2 secondary effects, although the player can only use 1 of them per turn (and only once that turn).
 * Across the board, the first secondary effect is: "During your Main Phase: You can Tribute this card you control; Special Summon 1 of your banished 'Necrolancer' monsters."
 * The other secondary effect is a mandatory effect that activates when the monster is Special Summoned while banished.  These effects vary depending on the monster, but typically center on gaining advantage by adding or recycling cards to the hand, or by Special Summoning additional monsters.

Extra Deck
The archetype has 2 Xyz Monsters:  A Rank 7 monster and a Rank 8 monster. Their purpose in the archetype is not disimilar from their Main Deck counterparts. However, unlike the high-Level Main Deck monsters, the Extra Deck monsters' effects are not especially "explosive", and are instead more support-based.

Spell & Trap Cards
While the archetype's monsters ensure that consistency and advantage are maintained, its Spell & Trap Cards are responsible for its most powerful plays. Once the archetype has had a chance to set up, it gains a prominent power spike and becomes capable of very impressive combos. Similar to the Monster effects, the Spell & Trap Cards have a primary effect and a secondary effect.
