Okay, two things:
1. What do you mean by capturing a spell? Does that negate the spell? Redirect it to the sorcerer? It would help if you would clarify in the notes section in the bottom table.
2. How exactly does this relate to Time, mechanically or thematically? I think it's more of an Aether kind of concept, with the dimensional things and stuff. Maybe even Gravity, with all the black holes and suctioning objects in.
mechanics:
Sand Sorcerer protects your fragile fate eggs,
after sand sorcerer skill is triggered, you can reverse time Sand Sorcerer to set up another spell trap.
you can also use in rhythm with sundial to deny opponent of creatures and spells.
theme:
the Sand Sorcerer sets up a time trap in an area.
when the enemy chases after the Sand Sorcerer,
the Sand Sorcerer routes the enemy to the time trap,
when the enemy casts a damaging spell,
the time trap is activated and time warps the area back
to where there is no damaging spell.
