It should be noted you always get your spell regardless of what opponents have revealed
Because your deck is 100% certified green energy, your opponent cant hope to defeat you with combat damage and instead must turn to mill, direct damage, enchantment removal, or other fiendish tricks
Any time one or more permanents would be phased out or anytime a card is put into exile, The War Doctor gets a time counter
These are incredibly efficient, after all
There are so many combat trick cards like Alchemist's Gift that can be lethal for a turn
Those subgrades are the features that every company evaluates (centering/corners/edges/surface), but having those individual grades displayed on a graded card is a nice touch some collectors/buyers might actually look for
