From S2x20 The Evil Queen;

"Regina: Teach me my mother's shape-shifting spell. Allow me to hide. 

''Rumplestiltskin: It took your mother months to learn that. You? Well, in a week, you'll be able to, uh, change your hair? Highlights? Maybe. ''

''Regina: If I can't do the spell, you can. Put it on me. ''

Rumplestiltskin: If I do,' you won't control it. And you won't have any magic while the spell is working.'"

You can use magic if you cast the Shapeshifting spell, such as Cora and Zelena do. However, having it cast on you means no using magic, not even the break to the Glamour. (Which makes you wonder why it isn't used to subdue magic users...)

This bit is just logical extrapolation; the Oz Clover casts the Glamour on the wearer, hence the wearer can't use magic whilst it's active. Also, the Clover works indefinately and even in the World Without Magic, which the Shapeshifting spell can't do. If you want to cover why Marian had her heart ripped out whilst Zelena enchanted her heart to prevent that, you could say the Clover has complete magic negation, so while Zelena was using the Clover her heart enchantment couldn't work.

Adam stated in an interview that the Clover casts a 'perfect' Glamour that would make a person's body, heart, soul etc look exactly like what they're mimicking, regardless of what device or magic was used to observe. However, the Shapeshifting spell depends on the caster's skill, and can be detected by someone knowledgable enough - such as Rumpelstiltskin (would has spotted fakes and Glamours before).

Which explains why Zelena would choose to use an Oz Clover, but not how she got hold of a Clover pendant in the past. It's not like she sucked it through the portal while she was a green smoke cloud. Was she even wearing it in the cell? Did she summon it from Oz? Well, she could have had it,  or found Robin's pendant that he stole from her.
