Sakashima the Impostor, Diluvian Primordial, Dominus of Fealty, Hypnotic Siren, Dack's Duplicate are all good creatures to think about. Polymorphous Rush, Stolen Identity,Harness by Forceare good spells to maybe include or think about. Baral, Chief of Compliance, Cloud Key, Goblin Electromancer, Mana Matrix are good for cheating mana. also a couple other possibilities are Jhoira of the Ghitu and involving suspend counters for high costing cards to come out cheap and early and use thing like Jhoira's Timebug and Rift Elemental to get the counters off quicker just a thought. i like the deck love me some izzet. here are the 3 izzet deck i have starting with my mizzex deck just in case there are cards i missed putting on here for you hope it helps +1 from me! Destroy Joy, Legends Of Izzet (legendary tribal) and Izzetdrazi (eldrazi tribal). good luck hope it helps.

@vao1221 sure. For the combo we absolutely need Sensei's Divining Top. For the sake of this example we will use the top with Cloud Key and Future Sight. Let's say you have both Future Sight and Sensei's Divining Top on the battlefield already. Then you cast Cloud Key calling artifacts which makes all artifacts cost 1 less. Now if you tap the top, you draw a card and put the top on top of your library. Since artifacts cost 1 less and you can play cards off of the top of our library, you can cast the top for free and tap it to draw a card as many times as you want. Each time you play it off the top, this counts as casting a spell. This is an advantage because Brain Freeze has storm, which means you copy the spell for each spell cast before it this turn. Ultimately, you would cast the top like 50 times and then mill our opponent for twice that. Future Sight can be swapped with Magus of the Future and Etherium Sculptor also works in place of the key. Let me know if you have any questions and upvote it if you like it please ;)

dotytron I've tried Heartless Summoning, and it may work if you build a deck around more and bigger creatures.

There are a few problems that make it a bad fit in this deck though.

First it's awkward with the 7 1/1s, you don't only have to bounce it to play them, but you can't play with any of them in play so you'd have to keep bouncing them first every time you want summoning out, that negates a lot if not all of the saved mana.

Second the cards we want to bounce the most, acid, pact and seas are not creatures. So summonings doesn't really unlock that aspect of the deck nearly as much as anvil.

Third there isn't a lot of need for more cost reduction in the deck. We are effectively running 6 anvils with the trophy mages so it's rarely a problem to find one, and you don't even want more than one anvil in play. Drawing more than one is already a dead draw, which is why I'm just running two. So summonings would be a dead draw if you have the anvil, and it's not like you couldn't add 1 or 2 more copies of anvil if you wanted to push the cost reduction further, but there is absolutely no need since only Doomwake giant benefits from more than 2 reduction.

Cloud Key would be a much more solid choice here if I wanted more cost reduction, it benefits all echantments and can be fetched with trophy mage, but in the end Semblance anvil is what has worked best in testing.

As I said before I like Future Sight Sensei's Divining Top. You play Etherium Sculptor or Foundry Inspector or Cloud Key and make all your artifacts cost one less. Play Future Sight and then play Sensei's Divining Top for free. tap the top draw a card put top on your library. Play top for free. You do this until you have your whole deck in your hand. Then I play Paradox Engine Aetherflux Reservoir to win.

These combos are "better" because they are generally lower CMC. Paradox Engine and Future Sight are the biggest spells at 5 mana and every piece of this combo works well without the other parts. They also win without giving anyone else another turn.

Should definitely look at Angelic Overseer, once she has Hexproof and Indestructable, your Odric will share it with the rest of your on field creatures. Another card you might consider is Cloud Key to help with lowering your creature costs.

You can replace Open the Armory, it's quite frankly useless, you have only 2 Godsend and because they are legendary, you can only have one on the field, Open the Armory is an utter dud.You might like Honor of the Pure, always good for mono white decks, Casual or otherwise.

KBgamer2010 on Kentaro, because you can

Consider running cards that can literally reduce the casting cost of your Samurai....examples are Urza's Incubator, Planar Gate, Stone Calendar, Helm of Awakening, Semblance Anvil, Cloud Key and Pearl Medallion considering its MonoWhite..With all of these artifacts being out, your Samurai should cost upto 10 mana less to cast, but that is as long as Kentaro is out on the field
