Playing "All the battalion cards" is probably more
dangerous than it might seem. Building purely around mechanics almost always is.
I really think this deck has some devastating potential if you take another road with it.
The main danger about Battalion, specifically, is that you only get the bonuses when you get to the point where it triggers. That's actually gonna be tough in a lot of games. And even then, although every battalion effect is "good", some are definitely better than others.
I think the two main questions to ask yourself are: "How do I ensure that I can turn on Battalion?", and "What can I do to get the most out of that effect when it happens?" (aka, how to I make this a strategy that will win me the game?)
Firemane Avenger is just a solid card with one of the best Battalion effects.
Legion loyalist is probably the best turn-1 play you could ask for. He just sets you up wonderfully and will make the game much easier to close out once you get ahead.
Tajic, blade of the legion is probably one of the best cards you could run in this deck. I know he's legendary, and that makes running multiple copies riskier, but having an indestructible dude in a deck that relies on having dudes cannot be a high enough priority for you.
The most important factors I can see for making Battalion work are:
-Getting dudes early on who are hard to get rid of
-Having some decent haste (maybe even dash) creatures in the deck to give the deck more speed and surprise.
I hope that helps some. I'm making a list of possible card ideas I'll share with you when I see you tomorrow.
(p.s. The reason
Lightning helix is expensive is because it's actually really good. maybe run Warleader's for now and if things work out consider upgrading
)
