I think Marin's Magic involves negating magic that involves the usage of space magic. Meaning like conjuring things out of nothing, which is like summoning Celestial Spirits, summoning equipments from the air, or teleporting from a location to another. Its different in ice-magic or fire magic because its creating those fire and ice while the mentioned before is previously existed.

Minerva can certainly teleport through her magic as seen when Minerva vs Kagura vs Erza or teleporting objects. She also manipulates the space around her, which is kind of what Marin is capable of doing, preventing anyone from using "space magic" around him.

I think... like in Yugioh (probably wrong), if I use a card that disable trap cards from being used, the opponent cannot use a trap card to attempt to destroy that card.
