We have seen this stat line before, a 3-cost 2/4 Bodyguard, in Little John - Robin's Pal and that card saw no play, even with an added bonus effect

a big Murktide Regent or Deaths Shadow will outclass a pair of 4/4 rhinos

If enough -1/-1 counters are put on Essence Channeler at the same time to make its toughness 0 or less, its last ability will see all of the +1/+1 counters it had when it died as well as the -1/-1 counters it had, and an equal number of each of those types of counters (plus any other applicable counters) will be put onto the target creature

The key differences are background requirements and edition accuracy
