Assemble the Legion because Tajic, Blade of the Legion needs an army behind him!

Hey man, looks like you're just starting with commander, let me tell you it's the best format there is.

So, to begin, 30 lands won't do with your Avg. CMC. and more so with the lack on ramp on those colors. I'd go with 36-38. There are some ramp in white though, Tithe, Gift of Estates, Land Tax, but old cards can get hard to find around. Besides, lands get on your hand instead of the battlefield.

You could try Burnished Hart, an inexpensive very useful creature to fix the colors. Myriad Landscape will find you 2 lands. Terramorphic Expanse and Evolving Wilds won't ramp, but they'll fix you colors and cost next to nothing. Mana rocks: It isn't by chance that Sol Ring is included on every pre-constructed commander deck. I like Fellwar Stone, most of the time it will get you the color you need. And while we're talking about colors, Command Tower is needed here as well.

Here are some stuff that you may cut to make room for those 6-8 lands:

Iron Star and Ivory Cup should be cut: 1 Life isn't nearly enough, less so in Commander. Also you have to pay for get that 1 life, just way too clunky, slow and expensive. Same with Survival Cache, 2 life isn't going to make much difference.

Akroan Crusader: You have 1 instant and 2 auras that could target him in order to trigger Heroic, so this creature would be a vanilla in practically every single game. Why would you target him instead of your commander or any other creature?

Blaze Commando: Similar problem as above, the tokens it can create are too situational. You need a better way to produce tokens.

Evangelize could work against some decks, maybe voltron is the best opponent to target. Still, cost is way too high for it to make it worthy in my opinion.

Stitcher's Graft: I really don't see the point on this one, maybe if vigilance were a theme in the deck, which is not the case.

Other stuff you should consider:

Wraths and removal!: Day of Judgment, Wrath of God, Fumigate, Blasphemous Act, Mizzium Mortars in case your opponents fill the field faster than you. For spot removal, there's Swords to Plowshares, Path to Exile, Condemn, Return to Dust

Battalion: If you like flavorful decks, this Boros mechanic that Tajic has can be complemented with other Boros creatures, like Frontline Medic to protect your creatures, Firemane Avenger as pseudoremoval and the more useful one Legion Loyalist.

Hope this helps.

Wow, thanks a whole lot, hfvalenz, for your useful advice!I am not a frequent player of Commander so anything helps, but you got really specific, and I can do most of what you said. Definitely adding Evolving Wilds b/c I have plenty of those, also a Burnished Hart will go in,too - I know I have one somewhere.

Since all my decks are For Real I cant commit to any other additions as yet, although Im sure Ill add at least one or two of the creatures w/ Battalion you suggested in near future...

Sadly, there are only 13 cards printed with the mechanic, and the most useful ones in my opinion were those I mentioned above. There is though, another Boros specific mechanic if you liked that suggestion, in the original Ravnica block, Radiance, that could be somewhat interesting. Check Bathe in Light and Rally the Righteous as examples that could prove both flavorful and useful.

Hey, I like the deck idea.

Just a few suggestions:instead of Turn Against, which costs 5, there are plenty of "gain control until end of turn" options. My favs are Kari Zev's Expertise (although it is less impactful in EDH), Grab the Reins, and Act of Aggression.

Instead of vigilante of justice, i'd add in more ramp/draw in the form of Solemn Simulacrum

Kari Zev, Skyship Raider has synergy with your general (although she is probably more for fun than function)

good luck!

Thanks, Vraska, for the card suggestions (and upvote)!

Took your advice best as I could for now by removing 2 white cards & replacing with Threaten and Traitorous Instinct - just picked up the latter yesterday. As soon I can find one or more of the three you mentioned Im ready to get rid of T.A. (especially like Act of Aggression), and I have a Simulacrum I can transfer from another deck.

Still cant find my Burnished Hart - where the heck did I put that thing??
