The Summon Black chip series are screen-dimming chips that summon a NightMare virus to move in front of the enemy and attack with a slash.
Summon Black requires a broken or hole panel in front of the user. If the user does not have a broken or hole panel in front of them whem the chip is activated, the chip gets used with the screen-dimming effect, but nothing happens.
The summoned NightMare appears on the broken or hole panel. It automatically moves in front of the nearest valid enemy target and attacks with a 1 long 3 wide slash. The slash is 
Sword.
A valid target is any enemy that is in the columns ahead of the panel the NightMare was summoned on that are not directly behind an object. The NightMare will not target enemies on the same column it was summoned on, nor enemies behind it. If the enemy is behind an object, the NightMare cannot target it because it cannot move directly in front of it. If there are no valid targets, the NightMare will leave without attacking.
Valid targets are: any enemy that is in the columns ahead of the panel where you summoned the NightMare, meaning it will not target enemies that are adjacent to the panel where you summoned it and enemies behind it, targetting the next valid target if possible (which in a 1v1 PvP battle, if the opponent is not a valid target, there is no other target, so after summoning NightMare, the NightMare will leave without attacking). valid targets also includes enemies that are NOT hiding behind an object, due to the NightMare's behavior, to attack the chosen target, it first needs to move in front of the enemy.
Competitive Overview
SumnBlk2 and SumnBlk3 are more valued than SumnBlk1 due to having high enough attack power to break 
LifeAur, as well as having favorable codes.
The chip itself is Null type, allowing the user to Beast Charge ths chips if necessary. However, the actual attack the NightMare performs is Sword, allowing it to decross Tengu Cross.
Synergies
Summon Black has natural synergy with panel-breaking chips 
Geddon or 
CrakShot to create cracked panels to summon the NightMare. Another source of cracked panels is with Panel Bug to crack panels while moving, particularly with Air Shoes to still be able to move on broken or hole panels freely.
The Summon Black series are among the highest-damaging Standard Chips in the game, with SumnBlk3 being the highest. The chips see use with Emotion Bug strategies to double their already considerable damage.
Counterplay
Summon Black requires an unoccupied broken panel or hole to summon the NightMare. If the enemy breaks panels and stays in front of one, be prepared for Summon Black. Standing on the panel the enemy intends to summon the NightMare from will prevent its summoning.
The NightMare must move directly in front of the enemy to attack. This makes hiding behind an object effective cover. Because the Summon Black series are screen-dimming chips, not only can the enemy cut in with a defensive chip such as 
Invisibl, 
AntiDmg, or 
Barrier, but if they cut in with an object summoning chip like 
RockCube or 
Fanfare to place an object in front of themselves, the NightMare will no longer be able to reach the enemy, and will disappear unable to attack.
If the enemy is using Panel Bug to break panels, 
Uninstll will leave them with the bug but without their programs. Without Air Shoes or Float Shoes installed anymore, their Panel Bug will start impacting their own movement.
Because the attack itself is Sword element, it will trigger 
AntiSwrd.
Version Differences
EXE6
All three versions of Summon Black are used, still favoring 2 and 3 for their higher attack power. Patch Cards provide additional synergy opportunities, such as PlanetMan granting B-Crack to effectively create holes on-cue.
