Forum:What must i do to become the thunder idol? :(

I played the monday event an became all evolve units but exactly every thunder units i need i didn't become

I play the quest level "attack from above" since 3 days without stop...and i have energy capacity about 75 an i use all of it

From over 100 tries and only 20-25 chances to become it...only 1 would have be succeeded...but one hit before i would won my smartphone was empty and because the game doesnt save (my favourite failure from the 2 or 3 fails about that) i haven't become it...what must i do to become this units

I don't know what i should do because it's sooo shitti i can't go on at the quest or somthing else :(
