How Blocker works
When an enemy Unit attacks, you may rest a Unit with <Blocker> to change the attack target to it. It has to be active (standing) to do that. A rested Unit can't block, so swinging with your Blockers is rarely free. Once the block is declared, the battle plays out between the attacker and the Blocker instead of the original target.
Blocker is a keyword effect, marked by the white <> icon on the card. Anything that grants, removes or checks for keyword effects will see it.
Rulings & edge cases
A block, once declared, sticks. If a Unit gains <Blocker> from a conditional effect, blocks, and then the condition stops being met mid-battle, the two Units still finish that battle. Losing the keyword does not undo a block that already happened (official FAQ ruling).
Blocking only changes the attack target. It doesn't stop 【Attack】 triggers that already fired, and effect damage such as <Breach> is not battle damage, so protections tied to blocking don't help against it.
Playing with and against it
Blockers are the backbone of defensive shells. High-HP bodies with <Blocker> tax every attack the opponent makes, and pairing one with <Repair> lets the same wall soak damage turn after turn. If you are facing a board like that, your answers are <High-Maneuver> attackers that can't be blocked at all, removal before the attack step, or buffed attackers that force bad blocks and trade the wall down.
