ok my rules for my fronteir challenge are...
set to lv 50
single or double if single battle each side gets three pokemon if double each side gets four
the opponent(you) can NOT use legendarys that are not allowed in battle tower but since am the legendary king i has a special program on my computer that is a randomizer so you give it like all the names of the legendarys and it randomly picks for me 3-4 legendary pokemon....so yes that includes darkrai but once you battle me i never use the same team twice
