I reach the lv 50 and unblock the function of ex wild card, perhaps, all of my cards stun in 100 + 5, how i can to expand my cards more and more levels?

get 1M SED, wait until Nutaku complete the 4th stage, or get 100 friends.

Level 50 give unlock +5 ex-levels
Level 100 give unlock +5 ex-levels
Level 150 give unlock +5 ex-levels ??
1 Mill SED unlock +5 SED levels
2 Mill SED unlock +5 SED levels ??
Complets stage 4 (can't be done atm) unlock +25 ex-levels

100 friends dont unlock any-SED levels!!

ty for clear a mistake

thanks for all explanations
