* AI: improved support of "as though mana" abilities (now computer can choose correct mana ability to pay, example: Draugr Necromancer);

* Dev: added card's LKI support of multi part cards (mdf/split/adventure);
* Dev: improved support of adding/removing counters from mdf cards;
* Draugr Necromancer - fixed support of mdf/split/adventure cards (#7620);
