The looter and the prowess body are doing two different jobs, and the design bet is that one feeds the other. A 1/2 with a draw-discard combat trigger is the descendant of a long line of small evasionless looters (Merfolk Looter without the tap cost, attached to combat instead) that smooth draws but rarely close games. Stapling prowess onto that frame changes the math: the noncreature spells you cast to enable a spells-matter deck also pump the body, and a pumped 1/2 connects more often, which feeds the loot, which finds more spells. The friction is the discard. The trigger is loot-shaped, not pure card advantage, so it rewards a deck full of cheap interchangeable spells you are happy to bin rather than a deck holding situational answers. That alignment is deliberate: the same density of cantrips and burn that turns prowess on is exactly the density that makes the loot costless. It asks to attack to do anything, so a 1/2 that taps out for combat is volunteering into removal range, and the body that grows only when you cast spells does nothing to defend itself. Built for the spell-heavy aggro-tempo shell rather than the control deck the looting half might suggest, it is a clean piece of synergy where neither half is exciting alone.
