Now for SCIENCE!
A card that has been leveled gives more XP than a level 0 card. The test is to see whether leveling an Easter Eggs card will give more XP than it costs to level.
Below is a chart listing the approximate amount of EXP an Easter Eggs card grants at specific level intervals, and how much EXP it costs to get it to the next level. Note: As I am currently in a clan that has level 5 Add Enchant the EXP numbers will be a bit off. My clan's Add Enchant level gives a 10% boost to EXP gained while enchanting, so I have taken that into account. The numbers below are a close approximation to what you would gain from sacrificing Easter Eggs at various levels without the benefit of the clan tech Add Enchant.
|Level||EXP Granted||Total EXP Cost to Level|
Even without counting in the cost to purchase or sacrifice cards we can clearly see that the amount of XP gained from leveling Easter Eggs is nowhere near the amount required to level it. The conclusion is clear. It is not cost-effective to level an Easter Eggs card before you sacrifice it.
