Does Rabadon's Deathcap give Forgefire Cape bonus damage?

Question

Accepted Answer

Yes, Rabadon's Deathcrown increases the damage dealt by Forgefire Cape.

According to the rules and FAQ:
*   **Bonus Damage** (granted by cards like **Rabadon's Deathcrown**) increases each instance of damage dealt by spells and abilities that already include a "Deal" damage instruction (Rule 715).
*   **Forgefire Cape** has the effect: *"When I attack or defend, deal 2 to all enemy units here."*
*   Because **Forgefire Cape's** effect already contains a "Deal" instruction, it is eligible to receive **Bonus Damage**.

When both gears are attached to the same unit, **Forgefire Cape** will deal 5 damage (its base 2 + 3 from Rabadon's) to all enemy units at that battlefield whenever that unit attacks or defends.
