when u upgrading cards - does it matter the Rarity of the crad u using ?

does a R3 Card, give me more experiance when i am uprading, compared to a common lvl 1 Card ?

did anyone tried to upgrade a card using R4 ? how much does that give.

would love it if someone can post a breakdown - how much XP does Each lvl card give.
