add another Tajic, Blade of the Legion too many people run Tragic Slip , and there isnt a point in having 5 Tragic Slip lol

I haven't really looked at my sideboard for the deck yet, but thanks for pointing that out! I do like Tajic a lot, but I don't like drawing a legendary when I already have one in play, so I'll try it out with two and see how it goes.

The "Legend Rule" only applies to Legendary Permanents of the same name. For example, you can have a Tajic, Blade of the Legion and an Aurelia, the Warleader on the battlefield at the same time without any issues.

Rohnur: I know that. My comment was in regards to putting in a second Tajic. Thanks though!

Hey no problem, I just misunderstood the comment.

I'm thinking about building a deck similar to this I'll maybe include Warleader's Helix in mine

I like the idea of Warleader's Helix but I don't like how expensive it is. I feel like there is more that you could be doing for 4 mana. If you do end up making that deck post it in a comment here and we can trade ideas.

I'd probably want to run a few Cloudshift / Restoration Angel in here. Blinking Aurelia at the end of the first combat step gives you 3 combats in one turn. Potentially more.

"400.7. An object that moves from one zone to another becomes a new object with no memory of, or relation to, its previous existence"

Red White Black gives you lots of options, it all depends on what you want to get out of the deck. You won't need Imposing Sovereign that much unless you face up against aggro, so i would keep it in the sideboard. Blood Scrivener is usefull for stabilizing but seeing as you have quite a few 4, 5 and 6 mana cost things it's no so likely that you'll be using his ability. Underworld Connections maybe more reliable. Like the basis of your deck though, +1.
