Cheap factionless

Working here with the cards I have. So no Varret, Hero-in-Training, The Speaking Circle or alike...

Key way to win is to bring Prism Golem out in round 3, either directly or through Worldshaper's Staff.
This would be followed by either a 5/5 Sentinel in round 5 from Okessa's Audience, a 6/6 Pumpwerks Monstrosity, or a Caiphus, Wandering King the round thereafter. Ocassionally, the Momentum Builder pulls off with Worldshaper's Staff, of which I'd put more in if I had.

The deck has only 26 units, but Replicator Engine the 4 Worldshaper's Staff and Okessa's Audience and Celebration add to keep the board busy.

There a quite a few cards with low play value remaining, which can be target for one of the 11 Plunder cards that assure a steady power curve to pump out biggies from round 5.

There is only little control in the deck, noteworthy are the 4 Waystone Alignment.
Lacking enough faction-less power cards, I keep one Justice Sketch and two Rune of Trickery.
