going to go ahead and commit this now as updating the ai decks to use this tool is going to be a huge task...i originally wanted to commit this when i had a substantial amount of ai decks using it, to show case how it makes a huge difference.

it is a feature that is for ai deck building
what it will do is as follows

#NAME:sample deck
#DESC:The forces of fire and nature unite. 
#DESC: 
#DESC:Can you withstand 
#DESC:their combined fervor? 

toggledifficulty:lotus petal|black lotus (*) * 4
grizzly bear (*) * 4
someCard (8) *4

notice the toggle dificulty?
syntax is ....toggledifficulty:easy card name or number|hard card (optional set if both belong to same set otheriwse use * ) *howmany

toggledifficulty:frying pan|machine gun
toggledifficulty:tomatoe|pumpkin (MBS) * 3
toggledifficulty:tomatoe|squash
grizzly bear (*) * 4

the above exsample as easy will have a deck with:
frying pan
4X tomatoe
4X grizzly bear

and on hard it will have:
machine gun
3x pumpkin
squash
4X grizzly bears

the entire deck can be built with toggledifficulty cards....its not limited to just a single use.
you can also mix it up, some can be toggledifficulty some can be just like normal, you are not limited to having to have a complete deck of toggled cards...

if your currently selected deck has an over all win ratio of 65% or higher...this deck will have 4 black lotuses in it...if youre overall win with the current deck you are playing is below 65% then those 4 black lotuses are replaced by 4 lotus petals instead...effectively making it an easier ai deck...

note, the 2 cards used are exsamples...its a great way to show you the potential this change can have...an ai deck with 4 black lotuses will do WAY better then the same deck with 4 lotus petal...if you catch my drift...
