to get 15 (chest) rewards at max level Silver II at End season tip... spending 310DEC

hi there, sharing my strategy to get 15 rewards for end season...
you need to reach silver ii level..
to do so you need to have a power of 40000 plus, by renting Yodin Zaku, legendary gold foil... spending 294DEC, and rent mylor crowling for 24 DEC...
you also need to reach 1300 to 1500 power rating by winning matches, that is why i also rented mylor crowling because when mana cap is lower than 20, i use this summoner instead of Yodin Zaku...
the line up is your basic strategy, learned by playing or watching the turtorial before you start the game...
