Moonveil Dragon I've found to be underwhelming. You can use it to push through those final points of damage if you've got a lot of dragons swinging out but I've not used it in many games. How is Doubling Cube working for you? After seeing it in your list I've been contemplating trying it out.

That's what I feel about Moonveil. I never feel the need to tutor it. I swapped it out for the Hart.

The Cube looks good on paper. Only got it into play twice. One of the times early game without enough mana available to make it work. The second time it worked quite well. I think you should test it.

What I did enjoy though, was my Soulbright Flamekin even though people scorn at it.

Soulbright Flamekin is excellent. It gives your dragons trample, ramps, and can convert your generic mana from mana rocks into . Even better if you've got that Doubling Cube out. It also lets you pseudo-save mana from Braid of Fire for later in the turn.

I also never even considered Thornbite Staff; I haven't looked at his erratum in a while and forgot he is a shaman. The Staff seems really good with your sacrifice outlets, also works with dragons that deal damage with ETB effects; you just need more mana to tutor again after you sacrifice. It also goes infinite with Kiki-Jiki, Mirror Breaker and a sac outlet.

Yeap. I enjoy the Flamekin a lot. Its quite versatile allowing several shenanigans indeed.

Staff is nice and I did consider it for a while. But I already run it on several other decks and thought that I could do without it for the sake of my opponent's. On the other hand, it is great card that works with several creatures (Zirilan, Kiki-Jiki, Feldon...)... Might remove Leyline of Punishment for it...

No Balefire Dragon?

No. I only own one and that's on my Kaalia. I do need a 2nd and 3rd copies (1 if them for this exact deck). Just haven't bought it yet.

In the future I'll add it. Unless Kaalia parts ways with it... Possibilities... :)
