Prolly been posted before but I just seen it , thought it was nutty
Give a {boros Reckoner} lifelink with say like {gift of orzhova} or any lifelink card really then make him indestructible with a card like {rootborn defenses} or {boros charm}
Now you just need to deal damage to the Reckoner then use his ability to continue damaging the same Reckoner, continue until life is sufficient
Fun in a BWR deck with {Olivia voldaren} and {high priest of penance}. Use Olivia after the reckoner or priest is made indestructible for fun shenanigans
