Efficient Machines and Tactics Cards

[darknessbeholder]

Efficient Machines says that allied Sentinels characters treat Shield results as Wild results. How does this interact with tactics cards that roll dice, such as Scrap Metal? Is the Sentinel character that is activating the card rolling the dice involved so gets to use shield as wild? or is the player rolling the dice and therefore can't take advantage of Efficient Machines?

Yes. Efficient Machines will apply to cards like Scrap Metal.
