to get the card badge just lvl up the crypts and only the crypts and only make ghostly crypts so u can generate as much mana as possible. for ninjas i slow it down so the meteors are more precise and because u start with 100 and generate 10 off of each mana pool every second u can just meteor spam. once u are fully upgraded crypts start upgrading the temples so your meteors only cost 100 mana and do 200 dmg more and u will eventually get all 15 done brilliantly. this is the only way i could do so i highlt recomend it.
