Protection from non-targeting.
{2}{g}{u}{r}: Split Second. Choose spell or ability
on the stack that says 'all' or 'target'. Replace
the word 'all' with 'target' or 'target' with 'all'.
The spell or ability resolves with this ability. A
spell becoming a targetable spell cannot target
its owner or their permanents. A spell switching
to 'all' only affects all valid targets of the spell.
