Once demoted to a lower arena, can you still get the higher arena cards?

If I was in arena 4 but got demoted back to arena 3, will I still get the arena 4 cards?

Solution 1:

Nope, your chests are tied to your current - not highest - arena level. If you make it to the top and then fall back to arena 1, you'll get arena 1 chests with arena 1 cards.

Solution 2:

While what agent86 said is true, if you have any chests over from the higher arena, they will still contain those arena's cards. So yes, you will still get arena 4 cards but you will not get arena 4 chests. Therefore, the only way to get the arena 4 cards would be if there were arena 4 cards in the shop before you were demoted, or if you had any arena 4 chests.
