[still bug]Sapphire Medallion vs Capsize

[Xenias]

Describe the Bug:
Sapphire Medallion does not reduce Buyback costs.
3 Meddallion in battlefield, costs of Capsize are UU and buyback 1.
Total costs must be 3.
But in game, costs are UU and buyback 3.

Which card did behave improperly ?
Medallions, and cards to reduce total costs.(not mana costs)

Which update are you using?(date,name)Which type(Duel,Gauntlet,Sealed Deck)
Manalink july 2013: Odyssey, then Invasion of new features ! V2

What exactly should be the correct behavior/interaction ?
Total costs must be reduce.

I try to fix. If you want, show attachment.
I hope it will be helpful to fix.
* But some spells do not use function named buyback.
* And some spells (ex.Whispers of Muse) hardcoded?

Are any other cards possibly affected by this bug ?
Kicker is affected too.

[Gargaroz]

In the "buyback", "kicker" and "multikicker" functions the "get_updated_casting_cost" should be invoked in order to achieve a complete fix. Thanx for the help, I'll try to fix all the non-standard instancies.

[Xenias]

Thanks for reply, Gargaroz.

I think that is too hard problems.
But, I'm sure you'll do it.

[Gargaroz]

Again, hopefully all this is fixed now.

Appears to apply to original cc and buyback cost separately. Ex. 2 Sapphire Medallions in play and cast Capsize. It asks for UU, then asks if I want to buyback and if I say yes it asks for 1 mana for a total of 1UU when it should be 2UU. With 3 Sapphire Medallions it costs UU to cast and buyback is free.

1- The bug is a bit different now and it concerns only Sapphire Medallion and Capsize which is the only blue card with colourless cost both in it's casting cost and in it's buyback cost.E.g
-with 1 Sapphire Medallion everything is fine and 1 is deducted from it's casting cost.
- with 2 Sapphire Medallion 1 is deducted from it's casting cost but no deduction from buyback cost.(instead of 1 deducted from buyback cost)
- with 3 Sapphire Medallion 1 is deducted from it's casting cost and 1 is deducted from buyback cost. (instead of 2 deducted from buyback cost)
- with 4 Sapphire Medallion 1 is deducted from it's casting cost and 2 are deducted from buyback cost. (instead of 3 deducted from buyback cost)

2- There would be more cards with this problem if Sapphire Medallion honoured Sleight of Mind which it doesn't.fix

[Korath]

No need for Sleight of Mind to find other cards since Sapphire Medallion is part of a cycle: Jet Medallion, Ruby Medallion, Emerald Medallion, Pearl Medallion. (They should still all honor Sleight, of course.)

Medallions honor sleight in commit 36c05292.
