How could this end up in Chalice?

I started with this wanting to be a Praxis deck with Amaran Stinger, Amaran Armadillo and Shingane Forge... well somehow Forge turned into Crystalline Chalice...
Then, when i got along creating this mess, i again ended up having no use for all my legendary cards... seriously, i wanted it to become shiny, but as you see it became sorta budget... why does this always happen to me?

The plan turned out to fill the board with 4+ health units using Crystalline Chalice and removing threats with Deadly, Equivocate, Lightning Storm & Hailstorm, once cleaned grap Accelerated Impact from the Market and off you go

I dunno why, but Crystalline Chalice and Accelerated Impact are seriously in love.

Some Cards are just there to make the Deck more fun, to me that is. Unraveling Fanatic for example. The deck consists of massive card draw ability and thus UF seemed the right addition to me, once we reach late game.

Also Pit of Lenekta deserves a place in this deck, because it can become a comeback machine.
