Hello,
First of all, i admit the name sounds funky

The ability i suggest is a feature for spell cards which makes them return to your hand after use, making them like permanents which cannot be destroyed, but has a very high casting cost. Some examples;
10

Destroy the targeted permanent. Returns to your hand after use.
10

Deals 5 damage to target. Returns to your hand after use.
7

Deals 4 damage to target creature. Returns to your hand after use.
12

Steal target permanent. Returns to your hand after use.
10

Inflicts 2 poison. Returns to your hand after use.
What do you think ?
