Lepellier

Training Grounds + Crab Umbra does not work. Umbra does not give the creature the ability, so it will still cost 2U to untap the creature.

Oracle of Mul Daya, Treasure hunt, and Amulet of Vigor?

But...I don't see "I Surrender" anywhere...huh...

The broodwardens are there to either keep the spawn alive until you can pull a Hellion eruption (2/2's have significant more staying power than 0/1's...) Or as another win condition. 2 Broodwarden's can easily win a game. The original layout of the deck ran both Broodwarden and Awakening Zone instead of Might of the Masses, but I found the price to be a little rediculous. As such, I would probably run comet storm instead of Banefire too. This deck can probably be put together for ~$20-$25 with comet storm instead of banefire and using either all basic lands or the refuges instead.

I suppose what I'd be most worried about is Lightning bolt. I'll probably just drop in dispel instead.

You should take a look at my venerated teachings deck. Looks very similar to this, but with a lot more levelling potential.

I guess really the big hit of this is the card drawing. I was thinking maybe throwing some see beyond's in the MB instead of the hatchling or crab. The main thing is that this deck is also to get a substantial amount of milling going to let Wrexial have his pick of targets.

Not only that, you mention the you can o-ring the eternity vessel. But it really doesn't matter. Eternity Vessel is a "may" ability, so you don't have to reset your life total.

Now, that looks more like a feasible deck with polymorph. :)

Might be useful if Polymorph was actually in the deck...

Same with Vesuvan doppleganger. No blue.

Sprouting Thrinax cannot be run. You have no red or black in the deck. (Or atleast your general isn't red and black).

I'll just fill the sideboard in with control like that to see what is necessary.

I would say run Hell's Thunder instead of Lightning Elemental as well.

You should go check out my Boros Allies deck. That deck has managed to consistantly keep ahead of spreading seas and has beat a spread 'em deck on numerous accounts.

I'd say run 4x Rhox War Monk MB, Sideboard 2x Quasali Pridemage and take out the 2x Rafiq or Finest Hour from the SB.

Small issue. Scion cannot copy Progenitus, seeing as Progenitus isn't a dragon.

Looks pretty good. Think about adding Lighthouse Chronologist for extra turns. Thus more levelling.

Splinter twin is most easily broken in allies. Splinter Twin+Kazuul Warlord=WIN.

I prefer running 65 cards in a deck. It's just something I do.
