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
