This faction is essentially the opposite of Sandy Lands, in the sense that Corn cards have defensive stats but floops that raise and lower attack. Sand has attack-based stats and floops that raise defense.
Corn Fields cards mainly seek to increase or decrease the attack points of the creatures on the board. This could be the creature itself, such as Cornball and Corn Ronin , the opposing creature, as in Archer Dan and Ethan Allfire , or even other creatures on your side, like for Legion of Earlings . Hence, Corn Fields decks are mainly setup to rush the opponent. Note that this is Jake's favorite landscape in the episode "Card Wars" (Season 4, Episode 14 of Cartoon Network's 'Adventure Time.')
