Well I think I've seen this deck before :P But now that's it's on tappedout and I can actually see it properly, if you're officially titling it a combo deck then you might as well have a few more ways to be obnoxious. card:Yawgmoth's Will is obscene with almost anything and particularly tutors, and speaking of tutors you should have Vampiric Tutor and maybe Beseech the Queen . Instead of Path to Exile you might as well have Swords to Plowshares instead (or in addition to)

I don't see Sigarda, Host of Herons does much for you honestly, other than just being a helpful beater. I'd rather have another tutor

Oh and as a combo deck, you might want some serious hand disruption like Mind Twist . The point is to disrupt until you can combo, you almost never win by smacking people in the face with cards like Sigarda.

Also why don't you have Corpsejack Menace ?

Adding a Mind Twist wont do much for this deck, If it's the only hand disruption I have. I want to keep the deck focused on combo and not take out a bunch of cards just for hand disruption.

But I have been thinking about taking out Sigarda, Host of Herons to add in another tutor like Vampiric Tutor .

Just added Corpsejack Menace

If you can please recommend some newer cards to add to this deck
