Squeezing “Oomph” Out Of Your Deck: Did I Build This Right?

I know there has been a lot of talk about U/R losing a lot of its luster with one less pack of Lavamancer’s Skills; I think the combination is still viable, but the archetype has changed. I have had some success pairing the Mistform creatures with the blue and red Slivers, like Blade Sliver and Shifting Sliver. 3/1 Mistform Dreamers and 4/1 Mistform Seaswifts present your opponent with a small window of time to find their answers.
