Stampede Rider

The design lever here is the word "each." A 2/3 with trample for is a plain body, but the conditional buff checks in on both your combat and your opponent's, so once you have a heavy hitter (something with four power on the board), the Satyr swings as a 3/4 on offense and blocks as a 3/4 on defense. That two-way symmetry sets it apart from the usual anthem-style rider, which only cares about your own attack step: this creature keeps its enlarged toughness on the crackback, absorbing a hit it could not survive at its printed size. The threshold it wants is a mid-curve one, which places the card in the long red lineage of beaters that reward you for already having committed to the board rather than getting you started: it wants to be the second or third creature down, not the first. Trample is the piece that makes the extra power spendable, so the +1/+1 spills through a chump rather than getting wasted on it. It is a modest, functional expression of the "my big creatures make my small creatures bigger" reward structure, priced so that it only pays out after you have done the work of assembling a threat to trigger it.
