hmm I"m working on an unupped (no shard/nymph) deck - Currently basing my ideas on flooding. However even if flooded, you need some decent healing to heal up owl's eye, the 7-8ish fireflies. On top of that you need some powerful damage, yet protect those from owl's eye.
I started with death + flooding combo (bonewall / boneyard / vulture - boneyards main function is to fuel bonewall faster, as the skeletons boneyard spawns die too). However the initial bonewall is simply destroyed before it gets time to build up.
After that I went to water + dark, using steal to steal emphatic bonds for healing - water (drags, crawlers) was used for damage. However this was very-draw dependent. As owl's eye/shock wave/fire bolt keeps wrecking your creatures. It was doable, but only if the opponent didn't get a flying owl's eye in his first 5 cards. AND you have a fast start (capable of stealing owl's eye a few times and also 2-3 bonds).
The only combo that might still work is fire+water, using steam machines to outdamage him, and deflags for owl eye control. Problem then is once again you have no healing.
Anyone else trying to build a non-upped/shardless deck for this?
