Better Ai: Foreach training, reduced Eff on "levelingup" based on cards in hand/maxxed in 2nd main, added a selectAbility() call after lands are played and after all cards were searched if none were found to play. after much playtesting i found that if given the chance to find an ability BEFORE playing cards, Ai does dramatically better during a match, the same goes if its given a chance to find one after it looked for stuff to play.

with this change please try playing a few matchs against vanguards chosen and wraith feast, my 2 most favorate decks to fight now. youre in for a treat :)

keep in mind that even tho ive taught Ai Foreach in a somewhat crude manner it still does not understand how much mana it can gain from a foreach manaproducer, and this does not make it suddenly use dark ritual correctly. however this change was dramatic enough that i wanted it in for 14.1

this is also still under massive play testing, however no issues were found so far with it as it is presented here.
