Correct. There will be an "On an adventure" overlay card in booster packs if you need it.
As a discard-player at heart, I'm not too impressed, might be worth a sideboard if a black deck
I've been on the hate train for this set, but I can agree with this. I'm sure there will eventually be a "main story" again (Garruk is our anchor and Will/Rowan will almost certainly play a part going forward), but I hope they learned some lessons from pushing that thread so hard and we get it more in moderation along with some good, plane-centric stories that are disconnected from the overarching plot.
Yeah, that doesn't look like a knight, at all.
Even the Boros Legion doesn't have goblin knights.
This feels like a really on-the-nose reference to the Shardplate Brandon Sanderson's Stormlight Archive. Huge sword, and massive, magical armour that breaks off a piece at a time as it's attacked. You can even see the armour knitting itself back together with magic.
Danse of the Manse feels a bit Beauty and the Beast (the film at least, not sure if enchanted furniture is a thing in the original fairy tale).
Blue-red is all about drawing your second card in a turn. Many cards trigger or get a bonus if two cards have been drawn in a turn.
White-blue cares about artifacts and enchantments. Many cards get bonuses if you control one and a double bonus if you control both.
Black-green has the highest density of Food rewards. Cards key off sacrificing Food or using the Food for other rewards.
Red-white is about Knights going wide. Red, white, and black all are Knight themed.
Black-red cares about Knights and Equipment.
White-black is the slowest of the Knight decks. It wants to have a long game and trade resources frequently.
Red-green cares about your creatures not being Humans. Cards will get bonuses when non-Humans enter the battlefield or are in play.
Green-blue wants to ramp and use as much mana as possible. Food and Adventure are both natural mana sinks for green-blue to use.
Green-white is the main Adventure color pair. It has the highest density of Adventure creatures and rewards for adventuring.
