How to tap your own land

[Shatterhouse]

Okay.

You can sort of enable manual land tapping. (AWESOME!)

But you have to implement it on every single spell. (BOGUS!)

Anyway, here's an example. Normally this spell would cost 1B. First, we reduce all the colorless mana in its cost to zero while it's in your hand. Second, we add an additional utility cost to the spell that requires you to tap an untapped land. Third, we prevent the spell from being cast if you have less than two lands untapped. So when you go to cast the spell, the required swamp will tap itself, and you can choose any other land you want to pay the colorless cost. Seen here:

Code: Select all

    <UTILITY_ABILITY layer="0">
      <COST qualifier="Additional" type="Tap">
        <TARGET_DETERMINATION>
     Object():GetFilter():AddExtra( FILTER_EXTRA_CREATURE_UNTAPPED )
          return TargetLandYouControl()
        </TARGET_DETERMINATION>
        <PLAYTIME>
          ChooseTarget( "ChooseLandToTap" )
        </PLAYTIME>
      </COST>
    </UTILITY_ABILITY>

   <STATIC_ABILITY zone="Hand" influencing_zone="Hand" layer="0">
      <EFFECT>
         Object():DecreaseCost( 1 )
      </EFFECT>
   </STATIC_ABILITY>

    <STATIC_ABILITY zone="Hand" layer="0">
      <EFFECT>
   Object():GetFilter():Clear()
   Object():GetFilter():SetZone( ZONE_IN_PLAY )
   Object():GetFilter():AddCardType( CARD_TYPE_LAND )
   Object():GetFilter():SetController( Object():GetController() )
   Object():GetFilter():NotTargetted()
   Object():GetFilter():AddExtra( FILTER_EXTRA_CREATURE_UNTAPPED )

   if Object():GetFilter():Count() &lt;2 then
           CantBePlayed()
   end
      </EFFECT>
    </STATIC_ABILITY>

Or you could simply add the tap -> mana function to the lands and tap lands before you cast spells

Will there be a problem if the AI or the player taps the land like Icy Manipulator? or any instant spells that taps the land?

re: Kev, no, UTILITY_ABILITY works as an additional cost to cast the spell and cannot be responded to. It's not like the triggered ability I used to mimic phyrexian mana, which could be responded to if the casting of the spell triggered something like Dragon's Claw.

re: Iceman, you could do that, but then you still have the problem with multicolor decks using up the colors you'd rather save for later. I've seen the game sometimes prefer to tap real lands over token lands for some reason. Unless there's a way to turn basic lands off so they can't be tapped automatically... My pet peeve with mana tokens is that it makes games take way longer overall. But it's nice this way. Casting spells is still quick and easy.
