Does Assault trigger and go on the chain when attacking, allowing the opponent to respond before it resolves?

Ruling: Assault and Shield are conditional passive abilities that do not use the chain. They apply immediately based on the game state without using the chain.

Nuances:

• Assault and Shield are indicated by conditional keywords "while" or "if"
• Example: Assault X grants +X attack while the unit is an attacker
• Since they don't use the chain, opponents cannot respond to them before they take effect
