Man, I knew I should've researched this better. I tried to take it just on the originally posted examples and that was my mistake. Research must be done, for now I withdraw my original conclusion.
Ok, only thing I can find is that all of the (at least previously thought) self reducers have a condition.
Good call on the stuff against printed cost and I'll add Doppleganger to evidence.
However analyzing the individual card effects and their wording which honestly isn't very clear. I'd say.. that the advisor "for you to play" also tells me that its also only a passive ability to be used on successive cards. Really, even the "from the hand" text isn't really convincing and my only real supporting evidence is that it would be rather bad for this not to be true. As if it were the case then it would lead to many abilities becoming two types of ability. Currently we have somewhat clear identity of cost conditions (including reduction and additional costs) , passive effect, and triggered abilities and if an effect would become multiple types it could create some really undesireable situations.
Though Guardian Pillar is a bit troublesome as its a passive abilty yet within the ability it has a triggered ability but isn't a triggered ability. We have some rules that force a sqaure peg into a round hole but when it comes to that card it is making this debate increasingly difficult as it blurring lines that it shouldn't be blurred.
Really, I have a GIANT bone to pick with guardian pillar and this is actually one of the several problems I see with its current implementation. Thats another debate for a different day though.
Back on topic. bringing up Doppleganger its passive ability's wording also has me at a bit of a loss. It kind knocks out my "from the hand" ruling.
“When you play Doppelgänger from your hand, choose a nonunique character in play with printed cost X or lower. Doppelgänger becomes a printed copy
of that character.”
According to its clarification... this ability kicks in before it enters play in order for it to use play or enter play response effects. So by extention opens Pandora's box as it removes that last barrier I can come up with to say that it is only a passive ability that works on successive cards played.
After debunking (sorta) the "from the hand" theory, Fixer seems to debunk my "for you to play" theory as well.
Type: Character Faction: Syndicate
Cost: 3 Skill: 2 Icon: ©©(A)
Lower the cost for you to play Fixer by 2 (to a minimum of 1) if there is at least 1 Attachment in play.
So... yep. I'm out. The ONLY thing remaining is the lack of condition. Which is really really weak as it is not defined as something needed to seperate cost effects and passive effects. But thats the best I have to keep pandora's box closed.
