Some Changeling Questions

Question: Does Cloudpost mana for more changeling-cards because, in theory, they too Locus. Sticking to what I do not know, Locus is only land type (such as Swamp), or it may be creature type too?
Thanks in advance.
Answer: Locus is only land type. Creature types and Land Types are different things. Also there is no "Locus" creature type in creature types list.

Question: I apologize for asking this question if it has been answered before, but does a changeling creature also have the creature type of a wall? If so it would not be able to attack correct?
Thanks
Answer: It has every creature type, including wall. However, no creature types have any rules baggage on them anymore, so just having the creature type wall will not prevent it from attacking. Most walls have been errataed so they have the ability defender now, which works the same way.

Question: Does Coat of Arms work with the creatures Chengeling? I mean, whether they +1 / +1 for each of its type? They have all the same types of creatures.
Thanks
Answer: Coat of Arms
Free translation:
"Coat of Arms". Each creature gets +1 / +1 for each other creature in the game with its generic type of substance.

Does Coat of Arms work with the creatures Chengeling?
1. Effects of Coat of Arms extends to every creature.
2. Creatures with Changeling are creatures.
3. Consequently, the Coat of Arms and operates creatures with Changeling.

Answer: Yes, the works.

whether they +1 / +1 for each of its type?
Ability of Coat of Arms says nothing about "for every type of creature".

Answer: No, not receiving.

PS Like any other creature, a creature with Changeling get +1 / +1 for each other creature in the game with its generic type of substance. The number of overlapping types of creatures does not matter.

Question: Explain, please, can I get a creature with Changeling from deck with ability of Amrou Scout? Or rebel is not a Creature type?

Answer: All rebels card have errata about searching "REBEL CARDS". Now they have search "REBEL PERMANENT CARD". It means that Amrou Scout can search permanent card with changeling.
