Golgari Guildmage

Two mana of any combination of black and green buys a 2/2 that casts off either color, so it sits comfortably in an Elf shell, a reanimator pile, or anything in between. Once it lands, the labor splits cleanly along guild lines. The black half is a recursion engine that demands payment in bodies: sacrifice an expendable creature to buy back a better one, grinding an attrition fight into the dirt over enough turns. The green half is a slow, uncapped beater factory, stacking +1/+1 counters one at a time onto whatever needs to grow. Neither outlet is cheap; each wants five total mana to fire, and that price is the friction the design accepts in exchange for two repeatable engines welded to a small frame. The guildmages of this era all share a template (two activated abilities, one per color, on an otherwise plain creature), and this one reads as the death-and-growth pairing the Golgari were built around: things die, then come back bigger or come back at all. The rate kept it out of constructed contention, but the body holds the two-color identity in its purest mechanical form: a single card that is both a sacrifice loop and a mana sink without ever needing a second guild's worth of support to function.
