You might be worried about small creatures getting outclassed at the Commander table, but white is the home of small creatures, giving you tools like The Battle of Bywater, Dusk / Dawn, and Assemble the Players to extract the most possible value from your little guys

Hes also just a very cheap way to generate 4/4 creature tokens which you can keep alive more easily if you just dont distribute any bounty counters
