Effectivement, si tu retire une carte de la partie pour payé le cout du banc (Exemple une carte avec cout convertie de mana de %4)
Le cout convertie du banc sera de %W + %W + %4 = 6

Q: If have Infernal Kirin in play and play Swallowing Plague using four mana (x=2) does my opponent discard cards with converted mana cost 4 or 2? --Lukas Z.
A: The Plague's converted mana cost when played with X =2 is four. Anywhere but on the stack the X would be treated like 0, but Kirin look for the converted mana cost of spells (and the stack is where spells live).
*Extra*: Don't forget that converted mana cost may not be the same as what it costs to play a spell. For example, the converted mana cost of a Blaze played using Fist of Suns's effect is only 1 even though you spent . A pitch card such as Force of Will still has converted mana cost of 5 even if you removed a blue card and paid a life to play it.
The Betrayers of Kamigawa pitch cards are slightly different in that they allow you to pick a value for X (unlike Fist of Suns) and then you have to pith a card of the right color with converted mana cost equal to X. With those cards, the X is included even though playing the spell cost you no mana. For example, removing a Cranial Extraction ( %3 %B ) from the game to pay for a Sickening Shoal ( %B %B %X) would make a Cloudhoof Kirin mill for 6 ( %3 %B converts into 4 for the Shoal, then %4 %B %B converts into 6 for the Kirin).
