Spell Refactoring Additional Cost

Currently:
Spells that has "As an additional cost to cast this spell" like Discard a Card like `Tormenting Voice` use this as part of their cost for the spell

```
Name:Tormenting Voice
ManaCost:1 R
Types:Sorcery
A:SP$ Draw | Cost$ 1 R Discard<1/Card> | CostDesc$ As an additional cost to cast this spell, discard a card. | NumCards$ 2 | Defined$ You | SpellDescription$ Draw two cards.
```

Maybe better?
```
Name:Tormenting Voice
ManaCost:1 R
Types:Sorcery
S:Mode$ RaiseCost | ValidCard$ Card.Self | Activator$ You | Type$ Spell | Cost$ Discard<1/Card> | EffectZone$ All | Description$ As an additional cost to cast this spell, discard a card.
A:SP$ Draw | NumCards$ 2 | Defined$ You | SpellDescription$ Draw two cards.
```

it might help us for coping cards if the "intrinsic" cost of the spell is only its mana cost?

then we might better differ from which static ability the additional cost is coming from in case of "linked abilities"?
