Ruthless Instincts

A modal combat trick that hands one mode to the player defending and the other to the player attacking, and asks the opponent to respect both until you commit at instant speed. On the back foot, the first mode turns a blocker into a wall with teeth: reach plus deathtouch means the creature trades up against anything in the air or on the ground, and the untap clause is the wrinkle that lifts it above a backwards Giant Growth. Granting deathtouch and reach to a defender is fine; doing it while untapping a creature the attacker had already written off (one you tapped to swing on your own turn, a mana dork, anything sideways) manufactures a surprise blocker out of a permanent that was supposed to be off the board. Green rarely gets to bluff this way. On the offensive, the second mode drops all that subtlety for +2/+2 and trample, the pump that shoves damage through a chump block. That two-sidedness is the whole point: a single card reads as a pump spell or a deathtouch ambush depending on the board, and the opponent has to play around both lines because they cannot see which half you will pick. Decision-density like this is the kind of design fair-combat green leans on to give a common-looking trick real texture.
