Chase cards like Mox Amber (retro) and Demonic Tutor (borderless frame break) lost between 1/3 and 1/2 of their value after their respective reprints with lower-end cards losing even more
There are incredibly powerful cards in this deck, like Trazyn the Infinite which gains all activated abilities of artifacts in your graveyard when hes in play, and Biotransference, which turns all your creatures everywhere into artifacts, spreading the Necron influence across your deck
Two big things happened: Each card got a type (Creature, Instant, Sorcery, Enchantment, etc.)
Seriously, the card is a mix of Hornet Queen and Avenger of Zendikar, and like almost all green decks, it goes well with Doubling Season
With no chess clock for best of one gameplay, it can lead to very, very, VERY, long games if the losing player chooses not to concede
