Trying to work out what each of the Attack Patterns in Eye of Judgment do can be confusing - inconsistancies with the icons make things hard to keep track of. Here is a list of each Attack Pattern in the game, and how each one works.

Standard
The basic Attack Pattern. Attacks the target directly infront of the card.
Standard Ranged
A simple ranged attack. Attacks the target 1 Field away from the card. This Attack Pattern is a standard attack, not Magical, so it is effected by Blind Spots, Dodge/Protection etc.
Lancer
Attacks all targets infront of the card. Creatures using this Attack Pattern will also hit your own cards if they are infront or behind an enemy card (if there is an enemy card to start the attack).
Selective Frontal
Select one of the enemy cards from the direction the card is facing. This Attack Pattern will hit that card. It will not hit your own cards like the Lancer Attack Pattern does, but it will only hit a single target.
Selective Arc
Select one target, to the left, right, or infront of this card. This Attack Pattern will hit that target.
Selective Full Circle
Select any one target next to this card. This Attack Pattern will hit that card. Creatures using this Attack Pattern generally have no Blind Spots.
Left/Right Strike
This Attack Pattern will hit any targets directly to the Left and Right of this card. If one of the targets is an enemy, and one is your own card, your own card will be hit too.
Front/Back Strike
This Attack Pattern will hit any targets directly to the Front and Back of this card. If one of the targets is an enemy, and one is your own card, your own card will be hit too.
Arc Barrage
This Attack Pattern hits any targets directly infront, to the left and to the right of this card. If any of these cards are your own, they will be hit too.
Full Circle Barrage
This Attack Pattern will hit any targets directly next to the card, including your own cards.
90 Degree Left
This Attack Pattern will hit targets to the front and left of the card. If either of these cards is your own, it will be hit too.
90 Degree Right
This Attack Pattern hits targets to the front and right of the card. If either of these cards is your own, it will be hit too.
Long Range Side Strike
Select any one target to the left or right of this card, up to 1 square away. This Attack Pattern will hit that target only.
Long Range Arc Strike
Select any one target in front, or to the left or right of this card, up to 1 square away. This Attack Pattern will hit that target only.
Full Long Range Strike
Select any target from the front, back or sides of the card, up to one square away. This Attack Pattern will hit that target only.
Standard Magic
Select any one target from anywhere on the board. This Attack Pattern will hit that target. This is a Magical Attack and will not be effected by Blind Spots, Dodge or Protection.
Magic Blast
Select any one target anywhere on the board. This Attack Pattern will hit that target, and any other enemy cards directly next to that target. This is a Magic Attack and is not effected by Blind Spots, Dodge or Protection.
Magic Nuke
This Attack Pattern targets every card on the board. Note that this Attack Pattern is often subjected to special rules which exclude certain cards from the attack based on Element or Field Type, and will sometimes require a target to be selected as a result. This is a Magic Attack and is not effected by Blind Spots, Dodge or Protection.
No Attack
Cards with this Attack Pattern may not attack (and can't Counter-Attack as a result).
