The main drawback with a card like this is that you might end up having the entirety of the table looking your way afterwards
Hardened Academic Hardened Academic is substantially better than random creatures that grow when cards leave the graveyard because its counters can go anywhere, so you gain great flexibility on top of a cheap threat
