Forum:Spell counters on set monsters?

Alot of my cards mass spell counters when a spell card is activated. let's take "royal magical library". if i set it (face down defense) and then activate a spell card will it obtain a spell counter or does it have to be face up. Also, can i activate it's effect while face down? that kinda goes along with roulette barrel and snipe hunter. thanks Stigles 21:37, 27 June 2009 (UTC)
