Metallic Mimic in place of Oath of Ajani maybe, sure Ajani can get more counters at once but then becomes obsolete since your only running one walker

Vault of the Archangel in place of Reflecting Pool as a test? If your mana colors seem to typically work out the added ability to give deathtouch and lifelink, combined with Archangel of Thune can make things big real fast.

Stoic Angel over Moat for a slight 'budget' cut and another angel :P But yes i know it won't have the same impact

Sublime Archangel to replace Platinum Angel or Exquisite Archangel to give an alternate win con, attack with one super powered angel, leaving defense up incase you don't have vigilance, or to avoid losing the board state to something like bouncing or exiling all attacking creatures

Ugh can't edit my last post, anyway I didn't count personally but i see Defy Death under two categories, and while it makes sense since it fills both roles just wanted to make sure that the deck doesn't have 2 copies by accident

I'll try the vault, along with the mimic.

Stoic Angel has its own drawbacks, it does mean that if Atraxa and Marshal aren't in play, stoic will prevent me from doing a lot of damage.

Since I don't really like exquisite angel that much, I'll test sublime out.

Also, if you change the categories back to a default one (Type, Converted Mana Cost, etc) you'll see that there's only one copy of each card.

Thanks for the suggestions DarkEclipse18
