Magical Citadel of Endymion vs MST

Please correct my following thoughts!

• Let's say I have a face-up Citadel with no spell counters and my opponent activates MST.
  MST resolves destroying the Citadel, before any counters are put on it.
  
  
• Let's say I have a face-up Citadel with one spell counter on it.
  My opponent activates MST, chained with another MST.
  MST resolves but Citadel removes a spell counter and is not destroyed.
  After the first MST resolves, Citadel gets a s.counter.
  The second MST resolves but Citadel removes a spell counter and is not destroyed.
  After the second MST resolves, Citadel gets a s.counter.

...right?

First one: I guess that it won't get destroyed cuz spell counters are placed when spell card is activated, not when eff resolves! So, Spell counter will be placed b4 MST destroys citadel!

Second: You are right in the second situation..

Guess I answered my question myself =.=

Indeed. That would be a little bit unfair ;)
