With this latest update I've hopefully added more archetypes into my cube so everyone can have a decent deck to play with rather than a hodgepodge of spells.
The first archetype I wanted to focus on was the UR Izzet Blitz deck that is possible. Alternatively this could be called the Spells Matter archetype (or the Kiln Fiend deck as Kiln Fiend kind of popularized this style of play a few years back as well as on the MTGO Pauper scene) as it depends on getting enough instant and sorcery spells to power the creatures that kind of depend on it.
The main idea behind this deck is to draft the following creatures (hopefully most, if not all of them):
and then enough instant and sorcery cards to support them.
I figured flashback and rebound cards would be useful as they are effectively two for one spells and they can activate the creatures abilities twice. So you would want spells like:
After that, the rest of the deck should be filled with more bounce, counters and removal and maybe some cards that recycle spells like Archaeomancer or Mnemonic Wall.
The basic plan then is you want to clear the way for your creature(s) with spells (which incidentally makes your creatures bigger), then attack and burst your opponent down with your big creatures.
If that fails, you can hope to draw into a big finisher like an overloaded Dragonshift or Teleportal or just constantly ping them to death with a Guttersnipe or Fire Servant fueled burn spells.
This archetype isn't as obvious though for new players so it might not see play but I think it would be fun and I will probably try to force it next time my group plays just to see if it will work.
