Akroma's Memorial is an easy cut and will reduce your costs by about $6. I only run Memorial in decks that like to swarm. But with my own Bruna EDH, I find myself playing much more conservatively and only having 2-3 creatures on board at a time usually.
Whispersilk Cloak is unnecessary. Lightning Greaves and Swiftfoot Boots also grant hexproof/shroud on top of giving haste. And Holy Mantle , Spirit Mantle , Unquestioned Authority , Tricks of the Trade , and Steel of the Godhead grant evasion already and have better synergy with the deck.
Not a fan of Academy Researchers because it doesn't solve the problem of easily being put at a card disadvantage with Auras. I'd rather run Iridescent Drake to fetch stuff from my Graveyard rather than use up resources in my hand.
Vanishing is a must. Probably the best defensive Aura for the deck since a creature that phases out takes everything with it and is safe for a full cycle around the table.
Sun Titan ? He can function as a slower but more versatile Bruna. And the amount of card advantage he can net you is ridiculous.
Cut the memorial, i've been back and forth on it for a bit, i just happened to have one and was looking for a home for it.
also just realised that a large portion of my deck is 3 drops so Sun Titan will be pretty bonkers.
Phasing is an old, obscure mechanic. When something phases out, it simply ceases to exist. It doesn't leave the battlefield, so no "leave the battlefield" triggers happen. Anything that happens to be on the creature also goes with it: Auras, Equipment, +1/+1 counters, -1/-1 counters, etc. Unlike Flickerform , the creature doesn't come back at the end of the turn. Instead, it phases back along with everything that was on it at the beginning of your untap step, which means it doesn't get affected by summoning sickness. Phasing keeps your creature safe for an entire cycle around the table instead of just one turn, which is very nice.
And when something phases in, it just comes back. No "enter the battlefield" triggers go off. Phasing does have an awkward interaction with soulbond though. When a creature phases out, a soulbond ceases to exist. And since phasing back it isn't the same as entering the battlefield, you unfortunately can't rebond them.
nice vanishing sounds like what i wanted Flickerform to be, thanks a lot!
