You can also use Nalu Blessing:

This is an universal feeder that can be used in place of all feeder cards used to evolve protagonist cards to purple. For example, instead of a Terror lord, you can use nalu blessing to evolve a max blue shaman to purple. Lvl up nalu to 75+ with pumpkins
Can be received at Lv60, 70, 80, 90, 100. Four Nalu Blessings are issued each time.
But choose carefully. You get them only once if you reach the lvl's above after that never again.
