Saheeli, Filigree Master — ruling 1

For the first ability, you don't choose which artifact to tap until the ability resolves.

Saheeli, Filigree Master — ruling 2

If you manage to activate Saheeli's last ability multiple times, each emblem you get is applied independently. For example, if you have two of those emblems, artifact creatures you control get +2/+2 and artifact spells you cast cost {2} less.

Saheeli, Filigree Master — ruling 3

The cost reduction provided by Saheeli's emblem can never reduce the colored mana costs of an artifact spell.
