Elvish Handservant

The trigger fires on any player casting a Giant spell, which makes this Elf a parasite on scale itself: every haymaker your opponent slams onto the stack can feed a counter onto a creature that cost a single green mana to deploy. The flavor gag is the design. Elves and Giants are tribal antagonists, and this Warrior eats its enemy's bigness for breakfast, no mana spent, no investment beyond patience while the big spells fly. The asymmetry is the unusual part for a green one-drop: most growth-on-trigger creatures key off your own plays, but this one is just as happy to grow off the haymakers across the table. What holds it down is the condition it depends on. Outside a board actually slinging Giant spells, the body never budges from its 1/1 base, and even when the counters do come, they arrive a step behind the tempo of casting expensive creatures in the first place. It is the small half of a two-card joke about the food chain, the runt that fattens on whatever giants happen to be stomping around, and it earns nothing unless the table commits to the tribe it was built to prey on.
