Show distinct card type summary in graveyard view

**Is your feature request related to a problem? Please describe.**

For the purpose of easily knowing:

a) What cards I need to get into the graveyard to achieve Delirium
b) What cards I need to get into the graveyard to best pump up the P/T of any of the various Lhuygoyfs that care about the various different card types in one's graveyard

It would be very nice if the graveyard view showed the summary of all the distinct card types when viewing the graveyard.

**Describe the solution you'd like**

When viewing the graveyard, show the summary like so:

eg. 4 card types (instant, sorcery, land, artifact)

**Describe alternatives you've considered**

The alternative right now is to manually count these card types yourself by looking at the actual cards in your graveyard. This gets tedious as your graveyard grows in size.

**Additional context**
