However, a shortcoming of the simplistic method of counting card advantage is that Raise the Alarm and Kalonian Twingrove are treated as the same card
But in Standard, it doesnt take much for this to pretty cleanly answer Sheoldred, the Apocalypse for a mana and a token, out of reach of Virtue of Persistence
It's no fun playing with an unbalanced or underpowered deck
And best of all, you only need 4 copies of any card ever because all your decks share the same virtual card pool and you dont need multiple 4-copy sets of the same card if you want to reuse it in other decks (which is another reason why the secondary market is so well supplied)
With so many cards you often don't see all of them, and with 8 different ancient ones you can play 8 notably different games
#42: Gem Blenders (Back #3) The final iteration of the Gem Blenders card back is probably not what anyone expected, but I think its a highly competent redesign
