Mana Drain

[Trofast]

I was wondering if my opponent cast Force of Will for free ( pay 1 life and remove a blue card in his hand from the game ). Then I cast Mana Drain to counter it.

Do I get 5 colorless or 0 colorless from the Force of Will?

Thanks!

The converted mana cost of Force of Will is 5.  Playing it for free does not change that.

The mana cost is always what is written in the upper right hand corner of the card.  The only thing that changes this is a copy effect.

Great thanks
