Forum:Divine Magician Deity Endymion Help

You can Special Summon this card from your hand or Graveyard by removing 6 Spell Counters from a "Magical Citadel of Endymion" you control. When this card is Special Summoned this way, add 1 Spell Card from your Graveyard to your hand. Once per turn, by discarding 1 Spell Card from your hand, destroy 1 card on the field.

I have quetions on this card. It says you can special summon this card by removing 6 spell counters from that field magic card. Would that mean that I am still able to tribute summon this. If I do I am not able to add a spell card from my graveyard to my hand, but would i still be able to discard one spell card from my hand to destroy any card on the field?

Help pls, got this deck already but confused with the effects.
