Enchant creature
Expire (At the beginning of your upkeep, you may pay 1 life. If you don't, exile~.)
Enchanted creature gets +0/+4 and has "All damage that would be dealt to other creatures you control is dealt to this creature instead."
When ~ expires, sacrifice the enchanted creature, then put a +1/+1 counter on each creature you control.
In the wake of heroism lies a legacy much stronger.

I think you want a "may" in the reminder text for Expire. Otherwise, you're forced to pay 1 life each turn until you die, and the card will never expire.
