Starting from about half upped, including 6 supernovas, what should be upped first? Creatures for more damage? Pillars for faster lays? It seems kind of pointless upgrading fogs, cc's and ulitharid, since the quanta isn't being drained from any source. Anyway, great deck, I've already gotten two shards!
Things I consider basically vital:
-QTs
-SNovas
-Hourglasses
-Charger
-Pulvy
-Most of the recluses/frogs (i.e. enough to actually still rush at a reasonable rate)
Things you can probably do without:
-Discord
-Explosion
-Lava Destroyer
-Ulitharid
-Crusader
-Fog Shields
-Shockwave
-Steal
-Thunderbolt
Recluses and frogs (and charger for that matter) should not be used unupped because they no longer have the same sort of rush potential. If you attempt the deck without those upped, substitute mummy for flesh recluse and psion for phase recluse. Frogs may want to be swapped to forest spectres, not really sure honestly.
Having ulitharid upped is actually extremely helpful in order to give it more survivability and the ability to soak CC, but it isn't vital. The support stuff that only improves in quanta cost by upgrading can work unupped, but speed is pretty much the key to this deck, so having to wait an extra turn to play things can be a game-changer. Mono dark with devourer spam is quite common in bronze as well, so being shorter on quanta is probably going to cost you some games.
Keep that being not fully upped is going to handicap your speed and overall profitability. It'll still definitely
work (and undoubtedly spit out a lot of rares) as long as you have the basics upped, but you won't get the same results.
For other people who don't have
anything upped and are looking for a totally unupped version of this deck, I recommend
Antabow.
