I just... normally don't get that excited about core sets, so my expectations weren't that high to begin. I'm reasonably optimistic about it as a draft set, but it's hard to give a proper verdict on some of these (dungeons, d20) until I've played with them.
Personally I'm not wild on paying 4 mana and 4 life for my first divination in environments beyond retail. I think it's strong in the best case scenario, but even in Penny Pincher turns were often too constrained to crack clues, much less pay 2 life for the privilege to do so.
I mostly agree, but I've also 3-0d with decks whose entire game plan was Primeval Titan into Volrath's Stronghold, or full control decks that mostly win off of Nephalia Drownyard in lieu of developing their own threats.
To me the question is 'how many creatures do you need your land to create to be worth it'. You can run a pretty creature-light deck and still make several tokens from the land.
