Interaction: Madness and Chalice

[boasnapes]

Just a quick question...

If I discard a Rootwalla, and pay its madness cost(0), to my Bazzar when there is a Chalice for 1 on the table, is it countered? Also the same scenerio with an Arrogant wurm and a chalice for 5(wtf?)?

So to clarify, Chalice of the Void only checks the cost in the corner of the card right?

Thanks a lot guys.

Chalice checks for converted mana cost (the cost in the top corner)

Madness is an alternate mana cost.

Therefore, Chalice for 0 doesn't stop Rootwalla, but Chalice for 1 does.
