Challenge Mode/Superman Godfall/Standard/Challenge Battle 2

Lex Luthor is required in all matches of challenge battle 2. As usual, challenge battle 2 is by far the easiest - the opponents are mostly at normal bronze levels and the tier of your characters are not restricted: you can use your favourite golds and the opponents has about 1/10 of the health of the battle 5 opponents. Even for extremely new players with only bronze cards, this can be of use for them as the 6th match grants 4,340 power credits.

If you don't have any version of Lex Luthor, there is no need to dish out big money for Lex Luthor/Krypto at this point - just get the bronze Lex Luthor/Prime or the silver Lex Luthor/Insurgency, both of which has useful team buffs that would make bronze or bronze/silver only battles (1 and 3) much easier.
