Planar Chaos; What's Hot, What's Not

Hot:
Damnation; Wraith sees a lot of play; so will this Wraith
Extirpate; a sideboard must vs combo
Boom // Bust; so HOT, 'geddon is back and it's versatile
Dust Elemental; it's good cuz it has flash
Dash Hopes; typically anything that gives your opponent a choice is bad
Wistful Thinking; madness, if your opponent hand <=2 cards it's discard + mill for 2
Sunlance; this will see play but not in Boros, maybe in UW control
Sinew Sliver; because i like slivers and this is my list
Porphyry Nodes; reprint of Drop of Honey, again in UW control
Mana Tithe; if it's there they will play it
Calciderm; 'cuz Blastoderm was in EVERY green deck in the day
Voidstone Gargoyle; versatile but he's expensive
Crovax, Ascendant Hero; resilient removal
Stingscourger; he's no jellyfish but he'll do
Pyrohemia; just add some pro red creatures and instant deck
Retether; how can i break this...
Braids, Conjurer Adept; if my opponents hand is empty...
Temporal Extortion; find a way to recur this, Anarchist + Dust Elemental?
Urborg, Tomb of Yawgmoth; at worst it's a swamp

NOT:
Akroma, Angel of Fury; too slow for a fast deck, too easy to kill for a slow deck, she works with Momentary Blink tho...
Detritivore; recurring land destruct = fun
Lavacore Elemental; if someone can make this work it'd be cool
Torchling;
Null Profusion; cool but no draw step = death by discard
Dichotomancy; superior mill card, but nobody play's mill
