• 10/1/2008 Paying cumulative upkeep is always optional. If it’s not paid, the permanent with cumulative upkeep is sacrificed. Partial payments of the total cumulative upkeep cost can’t be made. For example, if a permanent with “cumulative upkeep <img src="/Handlers/Image.ashx?size=small&amp;name=1&amp;type=symbol" alt="1" align="absbottom" />” has three age counters on it when its cumulative upkeep ability triggers, it gets another age counter and then its controller chooses to either pay <img src="/Handlers/Image.ashx?size=small&amp;name=4&amp;type=symbol" alt="4" align="absbottom" /> or sacrifice the permanent.
