The packs themselves include 20 cards each with at least one rare, about 8 lands and a cohesive theme
These five cards are held back only by the fact that they are legendary, meaning that you can only have one of each in play, and they do not possess the basic land tag, meaning they cant be fetched by cards like Rampant Growth
What started out as a gimmick turned into something extremely real, and Combustible Gearhulk is one of the most impressive cards Ive seen out of the new set
Getting to double the effects of expensive and X-cost spells for just a one-mana kicker is already some amazing fair value, especially when you can opportunistically copy Faithless Looting and other smaller spells in between the big stuff
TL;DR: You won't be required to collect as many reprints to fill out your collection
It seems like once youve ramped into your 4-drops, youll be playing aggressively and attacking your opponents as often as possible
