I use deckstats to make decks with spoiled future cards, excluding blocks that will go off in new standart (so when new block come into play, I have ideas of decks to use). Right now, using interactive decbuilder, I need to point every card to look for expansion. I can't even sort by expansion.
I like interactive deckbuilder, but if it have "future stantart" button near "standart", which will
exclude blocks that will go off standart in the next block
release, and include future cards - it will be really helpful.
