Unbreakable Formation

Creatures you control gain indestructable
until end of turn.
Addendum - If you cast this spell during your
main phase, put a +1/+1 counter on each of
those creatures and they gain vigilance until
end of turn.
"One rarely succeeds without help form others.
If you need help, you can turn to me, or any of us."
