currently Heart of Kiran isn't directly a hidden keyword, but its ability still should be reworked into a better way to replace the cost

see the other cost replacer:

• "CyclingForZero" (Activation)
• "You may pay 0 rather than pay equip costs." (Activation)
• "You may pay 0 rather than pay the echo cost for permanents you control." (Effect)

After all are finished the logic for isStackingKeyword can also be changed to use Keyword class information instead of ugly NonStackingKWList.txt

[Hanmac]

@tool4ever i already started this with KeywordInterface.redundant

also related to CardTextChanges, i want the keyword teach about what part of the Keyword should be affected by Text Changes, so it would simplify this issue: #2512

If you want you can try to update the CantUntap stuff again (using CantHappen Replacement?)

[tool4ever]

about IgnoreEffectCost$:
the other 2 cards that use it to affect Players wouldn't really need to be done as Continuous either

• so the logic for it could be moved to work on generic StaticAbility instead
• to avoid some redundant code the CantSearchLibrary stuff should also be Static instead of RE
• this would allow cleaning up adding statics on Players (only used by Damping Engine it seems)
  • to make this work we might consider supporting more than one mode together, e.g. Mode$ CantPlayLand, CantBeCast

[Hanmac]

Yeah, the IgnoreCost is somewhat tricky, but I would like to see you try it

For the enchant creature ones, doing a Static that gives itself another Statics might not big of a problem

For the Player ones, yeah, I recently stumbled upon the Player addStatic thing only used for Damping Engine and I would happily remove it

[Hanmac]

@tool4ever can you help me take a look at Undiscovered Paradise?

During your next untap step, as you untap your permanents, return CARDNAME to its owner's hand.

Shouldn't this be able to be done as DelayedTrigger? Or something?

[Hanmac]

Removed note for Volrath's Curse and similar

CARDNAME can't attack or block. and CARDNAME's activated abilities can't be activated. are mostly left for Detain like Effects. See #7209

[Hanmac]

I really want to remove HIDDEN CARDNAME can't block., but for this, I need to make Detain merged first
