I have idea to create new skills,like Deck Master (+ 1 card is in your hand) but one with potion of your choice and second skill with item of your choice at start.May be higher chance to drop earlier one potion and one item earlier.
For example when i am building Goblin hunting tower set,Dungeon door i can have earlier or Necromonion for more waves in earlier game with 10 used skills.
