If a creature that has +1/+1 counters on it receives enough -1/-1 counters to cause it to be destroyed by lethal damage or put into its owner's graveyard for having 0 or less toughness, effects that refer to the counters on that creature when it died will see all of those +1/+1 and -1/-1 counters
Also theyll stab sleeves
Steward of the Harvest , for me, is the more interesting of the two
If you promise not to take this silly example too far replacement effects work like having a Magic Sharpie that allows the card to yell Scratch that! and rewrite some ability, rule, or event
IV seems to give this card a little more oomph than Chandra, the Firebrand did, and Im pretty sure bloodrushing a Ghor-Clan Rampager on a Phoenix is one of the dictionary definitions of a BIG GAME (TM)
Anyway, EDHREC only goes back two years, so it cant tell you why Touch of Darkness spiked in 2018
