Ronom Hulk

Text:

Protection from snow
Cumulative upkeep (At the beginning of your upkeep, put an age counter on this permanent, then sacrifice it unless you pay its upkeep cost for each age counter on it.)

Rulings:

• 7/15/2006 Ronom Hulk can’t be targeted by snow spells (though there are no snow instants or sorceries) or abilities of snow sources, it can’t be enchanted by snow Auras, it can’t be equipped by snow Equipment (though there are none), it can’t be blocked by snow creatures, and all damage that would be dealt to it by snow sources is prevented.
• 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.
