Here are some good Nethroi targets that have low power but make tokens or have good effects when they enter: Biogenic Ooze Blade Splicer Master Splicer Maul Splicer Sensor Splicer Noosegraf Mob Chittering Witch Creakwood Liege Akroan Horse Pentavus Deep Forest Hermit Deranged Hermit Nut Collector Duplicant Geist-Honored Monk Ghave, Guru of Spores God-Eternal Oketra Hornet Queen Izoni, Thousand-Eyed Tendershoot Dryad Trostani Discordant Trostani's Summoner Most of the above cards create creature tokens, so you'll probably want the usual: Doubling Season, Anointed Procession, Parallel Lives if you include a lot of them
And when it happens, some games will end after you turn one enabler into turn two Cathartic Reunion or Ox of Agonas into a lot of power
The first is that it enters the battlefield untapped, letting you use it right away, such that it only costs a virtual one mana to deploy provided you can make use of the mana it provides immediately
The ability also triggers if our opponent targets it with a spell, which makes it somewhat resilient to removal
That said, Id resist the temptation to stick some of the zero-drop artifact creatures like Ornithopter in
You can drop them early or free any time to break folks faces, and good free stuff is always good, but many in Commander might go with the 4/4 Wurms first in a Commander brew with 40 life to get too and trample too
