Lots of fun! Below just some ranting about the deck. A whole new outlook on 'control'; Izzet Devotion!
Kill all your opponents creatures with deathtouch, or ping and eventually swing in with heavy hitters, such as gods or big fliers. Stall the game with low mana cost toughness creatures and mana ramp into the big game winning creatures.
Tested Strengths:
Geared towards anti-aggro. Better against midrange. Keeps their creatures off the bored and holds well.
Tested Weaknesses:
Lots of creature removal w/ early aggro. (Black/turn 4 aggro victories)
Hexproof.
Some Synergy:
Lots of ping + good creatures + death touch = creature control.
(e.g. Flash IS into turn 4 equip gorgon)
Death touch, first strike boros reckoner = stronk
Ping staticasters off of boros reckoner to ping the player or to deathtouch ping a creature, while only using one artifact.
Niv-Mizzet likes death touch too! ;D
Staticaster (IS) clears all tokens with the same name with deathtouch (Bye, Pack Rat)
Ral Zarek- to untap staticaster or just give your hasty fliers pseudo vigilance. Ral Zarek to turn 5 'ramp' into Niv-Mizzet. Ral Zarek with Keranos to deal heavy direct burn.
Thassa with Keranos to ensure a bolt or land draw. Thassa with Cipher Hidden Strings to get extra IS taps, by being unblockable. Thassa with Cipher to exile lots of spells for Nivmagus food, while being unblockable. Thassa with Cipher to untap lots of lands and summon lots of creatures off of Purphoros triggers, while also getting lots of devotion to get lots of gods active.
Use any combination of Staticaster, Draco, Keranos, and Zarek to take down even big creatures.
Hour of need can easily become a win condition by giving a random blocker, turning a frostburn, nivmagis, or static into a 4/4 flier with "Flash"
Hour of need can also become a board wipe as long as you have DT staticaster ready, pinging all sphinx tokens. (Everything not hexproof dies, gods included)
Specific/Subtle/Card explanations:
===4 Ofs
Temple of Enlightenment- helps scry and cast Boros Reckoners
Nivmagus Elemental- although doesn't benefit from lots of spells, does work with hidden strings nicely, gives devotion to every god, and is an early chump blocker against super aggro decks
Frostburn Weird,- good devotion to all gods, can turn unblockable
Boros reckoner- lots of red devo, first strike DT is scary, lots of synergy with Staticaster
Izzet Staticaster-, Flashing in at crucial times you need devotion, or to deal that extra 1 damage. If you "Turn" a creature it becomes easily killable with Staticaster
===2 Ofs
Hypersonic Dragon- gives devotion to all gods (Over stormbreath not giving any to Thassa) Instant speed hidden strings (tap land)
Purphoros- With so many creatures coming out, sometimes controlling and doing a little burn here and there puts you in range to win.
Thassa, God of the Sea-; Scry is needed, fills 3 mana curve, gives an aggro win condition deck the ability to be unblockable when needed.
Keranos; Easy to activate devotion, keeps the izzet steam train going, gets under board states and control with bolts. Can also utilize death touch if necessary.
Ral Zarek- can 'mana ramp' make some creatures kinda unblockable sorta with +1, gives 2 izzet devotion, fills a semi void 4 drop area, can -2 twice for 6 damage to the dome, can +1 to get more Staticaster pings in.
Dracogenius; Pings can become board wipes, strong 5/5 flier. Can keep the deck's steam flowing by drawing lots of cards, gives LOTS of devotion.
===Other
Gorgon Head, lots of pingers, some first strike, some other wise weak walls or chumpblockers, all become scary.
Hour of Need, can easily become the win con of the deck, turning spent staticasters and small elements or weirds into 4/4 flying game winners.
Hidden Strings; mana ramp, unblockable, nivmagus food, pseudo vigilance. Fun card.
==========SIDEBOARD====
Sidebaords always reflect the meta. So this may not be THE sideboard for you.
Stormbreaths, I origianlly had the playset in the deck, but found I drew too many and needed cheaper answers, sooner. Still good, but worth it verse white when Hypersonic is an option to help Thassa.
=Going against white? Swap out dragons for dragons.
Glaring Spotlight, if hexproof is a thing, this is the answer. Plus random unblockableness. For 1, if you draw it, cool. Izzet hates hexproof.
=Hexproof or lots of blockers? Find the right time to activate.
Turn/Burn; "never a dead draw" Turn things into a weird and Static it for 1, killing gods, obzedat, boros reckoner, deso demon, baron, polukranos, all those creature aholes. Or just burn little aggro guys, or seal the win with a dome shot.
=Pesky small creatures, flying creatures, creatures with annoying abilities, lots of creatures, or big creatures causing a problem? Toss it in. Facing too much control? The burn can go a long ways.
Swag song and dispel; Getting the little unexpected niche counters works better than you think. Giving an opponent a 2/2 flier doesn't mean much against this deck with all its creature bolts. Most removal, advent, etc, are instant spells... Swag song covers most annoyances. Dispel ALMOST all.
=Removal, advents, flash enchantments, bestow, buffs, a problem?
Counterflux to make sure your permanents resolve verse control, or to make sure things like elspeth, Serenity, etc, the big boys, dont resolve.
=Control keeps countering you?
MAYBE SIDEBOARD
Dissolve- More generic counters.
Rapid Hybridization- More creature destruction, nivmagus food, or creature destruction response. Good against decks playing around your staticaster. Good vs, all those annoying rare and mythic creatures. e.g. blood baron, deso demon, obzedat, master of waves, polukranos
