Can anyone tell me at what level of rarity it becomes worth while to do a 4-7 evolution instead of a 4-1? I started playing recently and I have 2 of the 4-star cards (I forget what that's called - mega rare?) which I was planning to eventually do 4-7s with. is this worth while? so far I've been eveolving everything with 1 and 2 stars to 4-0 just to get the highest evolutions in my collection, and doing 3 stars as 4-1, but I have yet to level anything rarer (also are there any 3 star cards that are worth doing 4-7 evolutions with?)
