Perhaps there is already a feature that could help for this, but if not, would it be possible to put another column for card descriptions that would sort by alignment? This would make building Type 2 decks on Lackey a bit easier because then you wouldn't have to jump around for counting certain card types.
Maybe it would be more work than it's worth to go through and label every card, but I guess that raises the question: do people generally build decks straight from Lackey or do people usually build decks on paper or with cards before going through and putting the deck on Lackey? Especially if it's a fun deck that you want to just test out, building right on Lackey is the easiest, although maybe only for Type 1.
Thoughts?
