Cataclysmic Gearhulk destroy special card & more

[Aswan jaguar]

Describe the Bug:
1- Cataclysmic Gearhulk destroys also special cards - Rules engine for sure.
2- Cataclysmic Gearhulk doesn't prompt opponent to choose permanents to save at least if AI casts it.


Which card did behave improperly?
Cataclysmic Gearhulk

Which update are you using? (date, name)Which type? (duel, gauntlet, sealed deck)
Manalink dev 778ccb5 version - duel

What exactly should be the correct behavior/interaction?
1- Cataclysmic Gearhulk doesn't destroy special effect cards.
2- Cataclysmic Gearhulk prompts opponent to choose permanents to save at least if AI casts it.
Rulings concerning 2 have lots of points:
- 9/20/2016 First the player whose turn it is(so if it cast with flash on opponent's turn opponent chooses first) chooses permanents he or she controls, then each other player in turn order does the same. Each player will know the choices made by players who chose before them. All of the unchosen nonland permanents are then sacrificed simultaneously.
9/20/2016 A permanent with more than one type may be chosen as either of the types or both. For example, an artifact creature may be chosen as the artifact, the creature, or both. Choosing the same permanent twice this way has the same result as choosing it once.
9/20/2016 Cataclysmic Gearhulk will be sacrificed to its own ability if you don’t choose it as your artifact or your creature.
9/20/2016 Lands can’t be chosen and won’t be sacrificed, even if they have other types (such as an artifact land).
9/20/2016 If you don’t control any permanents of one of the types, you’ll still choose the permanents of the types you do control.



Are any other cards possibly affected by this bug?

Also if both players have a planeswalker at least if AI casts it you are prompt to select opponent's planeswalker which is found illegal and only works when you select your own which has a non-target symbol on it.

Also it seems that it counts the total number of permanents so only 1 creature can be on battlefield 1 artifact, 1 enchantment, 1 planeswalker.

Fixed sacrifice also special cards in commit 27a7e713.
Real remaining problem mentioned here: viewtopic.php?f=86&t=20369&p=230701#p230701 since they share code.
