Refresh: Defensive - At the end of this unit's turn, restore all health to full.
Refresh procs not after the Refresh card finishes its action, but after all allied cards finish their actions, that is, at the end of the card's owner's turn.
Refresh on Assaults do not proc if they are Diseased at THAT moment.
If the Refresh card is destroyed before the end of the turn, Refresh will not proc.
