many ppl think koaki is budget but it s really expensive (6sr from different boxes)... i dont see the worth of this waste of gems for a f2p ppl: spending gems in a deck that will be tier 1 only this season.
The spellbook deck was way cheaper only need to buy the structure deck thirce vision of ice a mini box got all the cards for it.. where koaki u need atleast 2 Canadia and open 2 main boxes twice i got my first diamond core when 30 packs were left
