The recommended agents for this W-Engine are arranged from most to least recommended.

Yesterday's Calls is a great weapon for Physical Stun Agents, and both Dialyn and Pulchra are available in the game. Dialyn is the best character to use with this W-Engine because it complements her abilities perfectly as she deals Physical DMG with her EX Special Attack.

Additionally, both agents can benefit from the increased Energy Regen while being off-field and take advantage of the stack bonus that provides the team with a temporary CRIT Damage boost.
