How do I get a high Rank?

[immeyourenot]

immeyournot calls it "20 - minuite S" and it actually works (use big things like chaos sorcerers for lots of damage, then combine them with concentration for damge of 20+ each turn!)

Aah the good old 20 minute S, another one of my great inventions. Even twink & twinb doubted its 20minuteS-ness at first, but it never fails. I have 2 special 20 minute S decks, that are not only great in a normal battle, but if you use them properly you are guaranteed an S in 20 minutes.

Either A chaos sorceror deck or a nano dragon deck works fine. After a while these get so pumped up with AP/MP that they are doing SO much damage a turn that time becomes completely irrelevant. I usually keep it up untill i have about 200 damage which usually takes 20 mins (hence the name) & i always get an S.
