The Toybox (unfinished and needs help)

I was looking at both Mishra, Artificer Prodigy and Zur, the Enchanter earlier and came up with some ideas. This deck will be difficult to make and I'm not sure if it will be playable at all but I'll give it my best.

Creatures:
4 Zur, the Enchanter
4 Mishra, Artificer Prodigy

Enchantments:

Artifacts: 24
Crucible of Worlds 2
Dragon Arch 2
Serum Powder 4
Jester's Cap 4
Aether Spellbomb 4
Necrogen Spellbomb 4
Pyrite Spellbomb 4

Mana Artifacts: 16
Lotus Petal 4
Lotus Bloom 4
Gilded Lotus 4
Terrarion 4

A few things, with Mishra in play you should be able to pull out 4 Gilded Lotuses for only 5 mana. That's pretty broken. Mishra's also great with Lotus Bloom, I think the ones he searches for go directly into play (but I'm not sure). Mishra works well with all the artifacts and can hopefully be played with Dragon Arch or something faster (Elvish Piper?). As for Zur I haven't focused much on that part at all.
