Broken, But Not Beaten

Until end of turn, creatures you control gain indestructible and may block any number of attacking creatures regardless of card text. (Flying, Unblockable, Protection, etc.)
Destroy all creatures that were blocked by
creatures you control this turn, gain 1 life for each creature that died this way.
When the dust settles, and shields lay splintered. Your knights will stand on broken legs for you. They will fight until their dying breath, and then some.
