What about Izzet Staticaster in here instead of Circle of Flame ?

Ever consider Cloudfin Raptor in place of Hypnotic Siren ? It evolves quite nicely with Ornithopter and Illusory Angel . You should check out my deck, Fun with Faeries. I would also take a look at Anger of the Gods if I were you. Illusory Angel has a toughness of 4 which dodges Anger, and it is a potential solution to your problem with creature counters. I'm not sure I'm sold on Scuttling Doom Engine in here, seems to me you want to keep your cmc down so you have have mana in case your opponent is feelin' froggy.

Staticaster is great for token and cloning decks, but falls short in more common decks that don't just spam out one or two creature names. Circle of Flame wards off lower strength non flying attacks in general, and can combo with polymorphist's jest to destroy all attacking creatures at instant speed.

Raptor is a better choice than Siren, if it was just strictly for aggro purposes. But in this deck, it seems Siren is also a back up for a particularly troublesome creature, and can be a response to a weakness of this deck, creatures with tokens. They may avoid the board wipe combo, but Siren can then swing in to steal that creature from them, give it flying, and swing in with a "killed by own creature" tactic.

Anger of the Gods would kill a total of 8 from his 18 creature base, and leaves all others open to a stray lightning bolt to kill. Since it's not instant speed, you can't sneak it in like you can other board-wide removal responses

Goblin Kaboomist would fit very nicely here

Shrapnel Blast and Ensoul Artifact targets, plus frog killlers

Anger of the Gods would also provide a lot of utility

Manbeast did a great job of covering Soul_Power's suggestions! Anger of the Gods was in the original version of the deck, but it would just kill off too many of my own creatures. Scuttling Doom Engine is pretty expensive but he combos so well with the frog cards and Shrapnel Blast I've gotta keep him in. I've been looking at Generator Servant to speed things up, but I'm kind of waiting to see how speedy the meta is post-rotation.

Necrotech I totally agree Goblin Kaboomist and Ensoul Artifact fit very well with the deck. Once I get some time, I'm going to work on fitting them in somehow!

Why not use Turn / Burn ?

Deathwish47, Turn / Burn is a great card, but it rotates out soon.

Hypnotic Siren just seems so weak here (and in general). with only 22 lands you're not going to see that bestow cost go off very often if at all. But After searching there is very little options in the 1 mana drop blue creatures (that wont rotate out). Hmm I get why she is there, i just don't like her (lol)...I might have thrown in some counter spells instead?

I found an edit that needs to happen, for sure. Swap out spark jolt for Spite of Mogis it'll always do at least one damage as spot removal, so it works for that combo, but then it can be used later game to crunch out some midrange annoyances. Plus it gives a scry!

I revoke my comment now, since I didn't notice spite is a sorcery, not an instant. Not a good trade for spot removal

Manbeast75 Spite of Mogis would be awesome if it were an instant!

Neffer38 I keep getting the comment on Hypnotic Siren , so that makes me think I should definitely look at it! I was thinking of trading her out for a set of Generator Servant s to speed up the deck or Goblin Kaboomist s to kill attacking frogs or create Shrapnel Blast targets. I am getting worried about about my cmc as Soul_Power mentioned. If I add the Kaboomists, I'd probably switch something for another shrapnel blast.

Have you thought about replacing Scouring Sands with Electrickery ? the scry is nice and all but i dont think it can replace a fully instant speed boardwipe

ranger290 Electrickery would be a perfect card, but I'm trying to keep it post-rotation.

You said " Frog killer and Shrapnel Blast targets all on the toss of a coin... gotta love it!"

How exactly does a coin toss give you the chance to target all?

Deathwish47 Sorry man! I think I screwed up grammatically. Is my modifier dangling? I meant I get the chance to keep Goblin Kaboomist alive, based on the toss of a coin. He produces Frog killers and shrapnel blast targets. I'll fix up the description!

If you add in Goblin Kaboomist you should definitely sideboard in some Ensoul Artifact .

ranger290 Good call man! I'm still figuring on what to swap out for them.

This is slowly starting to turn into my deck...

Deathwish47 Great minds think alike! The ultimate deck would balance the removal of the frogs, the speed of Ensoul Artifact, and the power of Scuttling Doom Engine and Shrapnel Blast . I think this deck really showed what the frog cards can accomplish, and now I'm trying to weave in the other elements to make it more balanced. Next mission... bring in Ensoul!

Also, not sure if you should have it mainboarded or not but Darksteel Citadel + Ensoul Artifact could be pretty helpful, provide a quick 5/5 indestructable if up against aggro decks or if they ever board wipe

Dudes... I just can't find a spot for Ensoul Artifact . To bring it in, I would lose the consistency of the deck. Also, I'm worried about card advantage. With most of my removal using two cards I am going to empty my hand very quickly. Any suggestions on what to take out for ensoul? Also, should I add something for card draw?

Divination is great for keeping cards in hand. With it being Red/Blue, drawing is not my strong suit. Divination is really all I've got for ya

maybe take out 2 Illusory Angel for 2 ensoul artifacts? and maybe 2 mountains for Darksteel Citadel ?

Illusory Angel is too valuable as a early to mid game crusher, dropping that down loses a good amount of aggro presence, a perk of this deck, Citadel should only go in if Ensoul does, but it doesn't seem Ensoul has a place in the deck, when it's set up to run like it is.

What happen to kaboomist?
