Do multiple Breakneck Mechs stack the "your mechs have deflect and ganking"?

Question

Accepted Answer

Yes, multiple **Breakneck Mech** units stack their effects, but with some nuances regarding how the keywords themselves function.

### Deflect
According to **RiftJudge FAQ #8475** and **Rule 735.2**, **Deflect** stacks. 
*   **Rule 735.2** states: "If a Unit has Deflect, or has been granted Deflect, and is granted Deflect by an additional source, the Deflect Value of all granted Deflect keywords is summed."
*   Since **Breakneck Mech** grants "Deflect" (which defaults to a value of 1 per **Rule 735.1.b.3**), having two copies of Breakneck Mech on the board means your Mechs will have **Deflect 2**. An opponent must pay 2 additional Power to target them.

### Ganking
While the **Deflect** stacks, the **Ganking** keyword does not stack in a meaningful way.
*   **Rule 736.2** explicitly states: "Multiple instances of Ganking are redundant."
*   Because Ganking is a passive ability that simply adds a permission to a unit's Standard Move, having it granted by two different sources does not provide additional movement options or benefits beyond what a single instance provides.

**Summary:** If you have two **Breakneck Mechs** in play, your other Mechs will have **Deflect 2** and **Ganking** (which functions the same as if they only had one instance of Ganking).
