Right now I'm updating the deck and I'm unsure about something. Would like to know your thoughts on it: I'm going to add Rishadan Pawnshop but unsure if I should remove Reito Lantern or Soldevi Digger. I'm more inclined on the removal of the Lantern due to mana costs (it activates for 3 mana while the other cards activate for 2). Yet it can help me agains reanimation attempts while the Digger forces me to pay attention on how I order stuff that goes to the grave...

Major updates ahead.

I would remove a dragon in all honesty. Reito Lantern is repeatable which makes it awesome.

One mana shouldn't make a difference most of the time so I'd suggest cutting the Digger to cut down on headaches

Ok. What about Spawn of Thraxes, Bogardan Hellkite or Ryusei, the Falling Star? Spawn seems nice and all but its an odd card that might require a build more centered on basic lands. I like it since it can be useful in the late game. Ryusei has the ability to earthquake for 5 which can be quite useful (and it is bound to die quite easily in this deck since its something I'd like to sacrifice), making it good tech against several decks. Hellkite does seem a bit subpar. Sure, I can distribute the damage any way I want.. But no matter what its only 5 damage and its flash ability is pointless in this deck.

I like Ryusei.

As do I. And I removed Magmaquake with the intention of adding it since Ryusei does a Magmaquake for 5. Granted, it doesn't hit planeswalkers but those don't see much play on my group. Sure, every once in a while one pops up but this deck should easily deal with them.

I would cut Bogardan Hellkite. It's worse than Spawn because the likelihood of you having fewer than 5 mountains when casting Spawn is pretty low. Sure, flash is nice, but you're not really playing much in your opponents' with this deck.

Why Braid of Fire when you only run 2 instants? "Any of this mana that isn't spent during your upkeep step will be removed before your draw step begins. You cannot save it to be spent on the card you will draw this turn." Otherwise it looks pretty good. Anything with Sneak Attack and Feldon of the Third Path while running monstrous creatures is great in my book.

Since you're running graveyard recycling/recursion you could run Wheel of Fortune for draw. I would also definitely add Rings of Brighthearth. It not only allows you to copy Zirilan's ability but also Kiki-Jiki, Mirror Breaker, Feldon of the Third Path, Magewright's Stone, and your fetch lands.

If you find yourself needing more ramp Solemn Simulacrum and Burnished Hart are both good. Blasphemous Act is a good board wipe and Fervor is good for giving Zirilan and Feldon haste.

What about Zealous Conscripts. Not only does it go infinite with Kiki. It synergizes with Feldon and you should consider adding Strionic Resonator because of all your ETB effects and so on.

Wow! Lots of suggestions. Thank youu guys. I'm going to address them one by one instead of replying to each one of you. Sorry but it makes it a bit easier. So lets see...

Wheel of Fortune is one hell of a card. But it isn't budget-friendly. Around here the cheapest one costs about 10, which is expensive for what I'm considering spending on a single atm. Sure, Sneak Attack is in the deck. But I have it since it came out (not sure if I opened it on a booster or not). Anyway, money is the only reason why that card doesn't make part of the deck. I listed on the maybe board Wheel of Fate but I don't think it to be that good in EDH.

Rings of Brighthearth seem cool. I still prefer Illusionist's Bracers though. From the (still little) test done to this deck, I'd say that mana can be quite scarce and the ammount of mana needed to run Rings makes me cringe about its use.

Solemn Simulacrum and/or Burnished Hart... I don't have any more available Simulacrums but I have several Harts. And the fetching is good. More so with Valakut in play. I'm unsure about what to remove for it though. Added to the maybes.

Blasphemous Act is a cool card and I did consider it at some point. I chose Apocalypse and Jokulhaups instead. They have a broader effect and can combo with Worldgorger Dragon in a very devastating way. Act too but Act gives more chances to my opponents to rise from the ashes while the other 2 don't.

Fervor was dropped for Hammer of Purphoros. As a matter of fact I should run both. But again, don't know what to remove for it. Furthermore, often I cast Zirilan without enough mana to activate it the same turn. That's why I'm not using more hasty options.

Zealous Conscripts is cute. But the playgroup dislikes infinite combos. Sole reason why I won't add it.

Strionic Resonator is interesting. Both Rings and Resonator suffer from the same problem (activation costs) but since I can only use Resonator once per turn, it makes it much more appealing (no need to live open mana for future activations; simple). I wouldn't mind comboing it with Scourge of the Throne for a 3rd attack each turn. Again, added to the maybe board. I don't have any (would have to acquire one) and I don't know what to remove for it. But I like it.

Now... About choices I made!

Bogardan Hellkite has indeed been removed. It is as you say: flash matters little and the 5 damage distributed as I chose is a bit lackluster. So, my question is either Spawn of Ryusei. Spawn targets a creature or a player while Ryusei deals damage to every non-flier...

Braid of Fire isn't there for the instants. The deck doesn't run, as you say, any ammount of instants that woul make this useful. Yet it gets me free activations for Zirilan of the Claw, Feldon of the Third Path, firebreathing dragons and any artifacts with activated abilities (which is the majority of my choices). Its free mana and it works quite well even if only on my upkeep. This card has been tested and proved good enough to stay.

Thanks for the suggestions thus far.

You might consider Ogre Battledriver instead of Fervor.

I hadn't thought of that. My dragons would like it quite a lot indeed. I'm also considering Heartstone.

To free up some space I'll swap my 3 looting sorceries for a Mad Prophet. That way I can add the Ogre and return the Taskmage to the deck.
