I playtested this vs. my Gisela R/W semi-aggro and it was so good though I won in the end Gisela doing over 21 dmg (Ride Down is very nice), the game last 30+ turns due to True Conviction, Archangel of Thune, Platinum Angel, and an Aegis Angel protecting the Platinum Angel (Again, it takes some serious removal to get them both out .-.). +1 definitely!

Open To Suggestions

I'd suggest Rune-Tail, Kitsune Ascendant. 30 life is pretty common in EDH, and while it's not indestructible it's close...

hereticloki Defiantly adding Rune-Tail, Kitsune Ascendant to list possibly in place if Gideon's Avenger

Thinking of getting Elesh Norn, Grand Cenobite as alternate commander.

No Gift of Immortality?

Here's my Rune-Tail list. It's probably got some other ideas you can grab too...

Safe Mode Engaged

Thinking of adding Resolute Archangel and Ring of Three Wishes unsure of what to get rid off.

I think Ballista Squad is one easy remove. After that, I'd look at some of the smaller effects you don't get a lot of use out of.

Things like Gossamer Chains and Reconnaissance can be very powerful in the right games, but just as often can be straight up useless. Those two jumped out at me as ones I could see situations where they're dead draws. I usually look for that stuff when trying to trim...

Thinking of adding Conjurer's Closet for synergy with:
Angel of Glory's Rise Angel of Serenity Archon of Redemption Sunblast Angel Twilight Shepherd and possibly Resolute Archangel if i decide to add it.
