Card Tips talk:Pitch-Black Power Stone

'While "Magical Citadel of Endymion" is active on the field, activate 2 "Pitch-Black Power Stones" then Heavy Storm. "Magical Citadel of Endymion" will not be destroyed due to its invincibility effect, while the 6 spell counters are transferred to it. Once there you may remove them to special summon "Endymion, The Master Magician" from your hand or graveyard. '

But won't you have to remove 1 Spell Counter to keep it in play? So, there will only be 5 Spell Counters...
