Triggers for when you draw cards
Double draws (Thought Reflection and Alhammarret's Archive are crazy with Arjun; this deck gets pretty crazy with one out)
Discard as a cost
Equal to number of cards in your hand
No maximum hand size
Ways to skip draws (so you don't deck yourself with a double draw effect)
