Clock Tower Prison

Clock Tower Prison
Field Spell

During each of your opponent's Standby Phases, put 1 Clock Counter on this card. While there are 4 or more Clock Counters on this card, you do not take any Battle Damage. When this card with 4 or more Clock Counters is destroyed and sent to the Graveyard, Special Summon 1 "Destiny Hero - Dreadmaster" from your hand or Deck.


When you have 4 or more Clock Counters, how does this "Battle Damage Prevention" work in relation to monsters. Can they still be destroyed in battle, or are they protected in a manner similar to Waboku?

Only your Life Points are protected.

In regards to it acting like Waboku, here is Waboku's current text:
You take no Battle Damage this turn. Your monsters cannot be destroyed by battle this turn.
