Alright, I've got the best reason as to why LeBeau needs a nerf soon.
Let's take a look at the colors. Every color has a focus of sorts. Refess, as we're finding out, is built around stalling and wearing out your opponent. Gowen deals ridiculous amounts of damage. Falkow is the control element, and has a lot of speed on its side. Lawtia is sort of an everyman color, but has a lot of regeneration and nighttime based effects.
Interesting. These colors actually match up pretty well to Magic's color (with the exception of Green, which appears partly in the base rules, its mana generating element). Much like Magic, as well, each color has a bit of the other colors in itself. Often times however, they're not as efficient (you won't see Red having protection from everything without White's help, for example). This is a key point of the color wheel in Magic.
How does this fly back to Alteil? Soul cards are technically colorless, since you're able to use them in any deck without consequence (Soul effects permitting). So, being rational about this, there shouldn't be abilities that exceed the potential of the color they're based off of (indeed, there is a lot of damage soul effects in the base set. Nothing against Gowen's Fire Tornado though).
This is where the game is broken. LeBeau's soul effect exceeds the potential of any card in the base set, with no drawback to mention (aside from it activating too early, or with few units in the grave). Refess, previously the king with its Raise Shield Grimore, can't even scratch the raw potential of a card which can yield 60+ DF under the right conditions without even costing you your play for the turn. Since this effect is also colorless, match it up with Lawtia and suddenly you have the much reviled Zombie Lord combo.
We have discussed that there are approaches to break this momentum. Unfortunately, I'm here to break further bad news. Each of these maneuvers breaks your momentum. Look back at my unit control thread. The two cards which can absolutely break Zombie fort's hold are both in Lawtia (again, one colorless because it is a soul). Assassin costs you your own unit to take out another. Merciless Death costs 6 SP to use. Playing Lawtia to Lawtia, anyone can call the Merciless Death coming up and backlash it if necessary. Assassin further fails if you have no units out on the field (which is more than likely if you need to blow units to activate it) and of course costs you momentum which you are probably seriously hurting for. Two other choice cards are Expert Sorceror (Blue's answer, doesn't kill momentum as bad and can be sped up enough to hit), and Dispel. Everything else is pretty ineffective since Zombie Lord can come back from the hit.
Yeah, this issue has been beaten to death. I just figured I'd give my take on it, so if you think I'm onto something, feel free to add, but if you feel like I'm ON SOMETHING, feel free to berate me. I already know Logress is going to get on my case (just kidding, the only way he's not on my case is if he doesn't look into this issue). Also, final disclaimer, these thoughts are on pure speculation and analysis just like everything else in this world oh boy what are we coming to etc etc.
