Forum:Skilled Dark - Citadel of Endymion question

Hi, I was planning on getting the Spellcaster's Command Structure Deck in the future and Magical Citadel of Endymion definitely seems like a great card. I know that Magical Citadel of Endymion cannot be used in place of Skilled Dark Magician's effect to summon Dark Magician, but I was wondering if when Skilled Dark's effect is activated and he is sent to the graveyard, do his 3 spell counters go to MCoE?

I guess my question comes down to: when a monster is tributed does it essentially count as being destroyed? Similarly this question could be asked if I were to use Magical Dimension tributing a spell counter monster with spell counters on it. I feel like I used to know the answer to this question but its been a while. Thanks!
