Okay some spoilerz, guys! In addition to the ones G.Moto already added.
Insight then, first off
Crucible of Worlds - Creature = Rumunap
Excavator. For the person that values a good ramp deck = me! I can't wait for this card, it is something that I was waiting for since Origins rotated and
Nissa's Pilgrimage went. It has also got to be great for Modern and EDH players! Fetch lands return to be replayed triggering those landfalls!
Wildfire Eternal spoils a new mechanic (
Afflict) which is seemingly great especially if you could give something that has it, shroud or indestructible. It's secondary triggered ability is powerful, especially if you could give your creatures skulk! (
Behind the Scenes) or Menace (
Graf Harvest/
Lord of the Accursed) - this card has amazing potential to be a real finisher, especially with the potency of zombies atm!
Adorned Pouncer? Now, this is an interesting card... it is a rare, with a pretty average Evergreen ability and an undisclosed new mechanic (Eternalize) for 5 mana. It is also a game day promo (don't hold out for it being great)
At first glance it appears relatively weak, so Eternalize must compensate for that, eternalize as of definition is to make something exist in perpetuity. Could
Adorned Pouncer be an
Insidious Mist?
Personally, I would never play this, even if it was hexproof and/or indestructible, as it doesn't give me enough for 7 mana. Assuming, I cast it and it resolves, and play the ability before someone casts
Magma Spray in response to the trigger. (I assume, therefore, it might be an alternative cost, pay its eternalize cost or base mana cost.)
Abrade, a sideboard card.
