Umbral Druid combines the Token shell with the huge tempo swing of a 0 Mana 4/4 with Rush. Malygos the Spellweaver, Living Seed, and Fungal Fortunes are powerful card draw in a deck that is mostly spells. This deck is still in its experimental stages: Malygos, for instance, may just be too slow.

The deck's main reason for running Umbral Owl comes from the powerful synergy between it and the combo of Ironbark plus Mark of the Spikeshell to gain a lot of stats for very little mana (and you can throw in a Solar Eclipse for even more 4/4s). If you're willing to craft it (or already have it) Glowfly Swarm is a board-filling spell that will also serve as an alternate win-condition to the Owls.
