Protection from colored spells (fixed)

[sumomole]

When I code Emrakul, the Aeons Torn, I found something that hasn't been noticed before, or it isn't the same as before, anyway, I haven't tried in DotP2013.
If you would cast a spell, when you choose target, the card is regarded as on the stack, so "protection from stack" can prevent it, similarly, when you choose target for a ability, the ability is regarded as on the stack too, but the card that has the ability not. So, protection from colored spells is easy to code, as the following:

Code: Select all

  <STATIC_ABILITY>
    <LOCALISED_TEXT LanguageCode="en-US"><![CDATA[Protection from colored spells]]></LOCALISED_TEXT>
    <CONTINUOUS_ACTION layer="0">
    if EffectSource() ~= nil then
       local filter = ClearFilter()
      filter:Add( FE_NUM_COLOURS, OP_GREATER_THAN, 0 )
      filter:Add( FE_LUA_CONDITION, 0, EffectController())
       EffectSource():Protection()
    end
    </CONTINUOUS_ACTION>
    <FILTER_CONDITION id="0">
    if FilteredCard() ~= nil and FilteredCard():GetZone() == ZONE_STACK then
       return true
    else
       return false
    end
    </FILTER_CONDITION>
  </STATIC_ABILITY>

If you find any problems, please tell me, thank you.

EDIT:I found I missed something, if don't add this code, the the spell card in hand can still be cast even if Emrakul, the Aeons Torn is the only creature on the battlefield, just can't target Emrakul, the Aeons Torn and will be back to hand.
