I originally was trying to leverage the fact Dovin, Grand Arbiter can gain loyalty points from going wide with +1 and can create more tokens with -1. I tried finding more cards that would allow more token generation while also looking at "instants" for Dovin's Acuity. I was able to get a decent spread and trigger combos, but there was no real finisher like a mass buff for all tokens. At that point the deck focus conflicted and I decided to keep a go wide/token deck for another time with Skycat Sovereign and drop Dovin's Acuity in that deck for more impactful cards.
Removed...
4x Dovin, Grand Arbiter four may have been overkill, but in the end it just didn't work with the theme for bouncing Dovin's Acuity constantly.
4x Rally for the Throne If no longer going for tokens this doesn't help anymore. It was nice since it was an instant to trigger on main phase, and if I leaned into plains more I was more likely to get the adamant for potential big healing.
4x Depose / Deploy The 2 cost tap and draw is helpful and being instant can trigger Dovin's Acuity RNA), but it was hard to really take advantage of the tap unless I waited until opponents turn or later in the game. The 4 cost option was a big hit on the deck since I was going wide, but since I am moving away from that I replaced it to better focus the deck.
4x Hero of Precinct One was a good pick for going wide, but keeping myself on the "instant" restriction made it difficult to really combo with more than a few times. Would benefit much more from a mostly multi color deck that wants to go wide instead.
4x Ajani's Pridemate was put in since I had a lot of ways to heal and needed lower cmc options. Since I've moved away from mass healing to just heal to keep me afloat, I removed them.
3x Castle Ardenvale without need for tokens I removed this in favor of mana fixing
Replaced With...
4x Opt scry and draw for 1 mana to help me dig, and can trigger Dovin's Acuity.
4x Deputy of Detention One of my favorite cards in U/W recently, and acts as one of my main removal methods while I get to late game. Great for aggro decks since they can use a lot of the same creature and the Deputy will exile all of them not just one. Same for tokens.
4x Elite Guardmage At first I was on the fence with this card, but I'm coming around to it. It's not super potent as a creature for 4 mana but if you break it down I see value. For 1 Blue mana you get draw, for 1 White mana you get 3 life, then for 2 colorless you get a 2/3 flyer. It's not amazing by any means, but it helps get me to the next few rounds with a minor flying threat if they don't have reach or low power creatures.
3x Cavalier of Gales I really enjoy the roundabout scry 3 draw 1 you get with this card (draw 3, put back 2 from hand) and at 5/5 it is a decent beater/defender. When it dies it also goes back into my library and gives me scry to help set up the next few draws. A combo I had from here a few times with scry lands is to put back two cards I don't want, drop the scry land and push the card on top to the bottom to get rid of it.
3x Dream Trawler I feel it is a bit high CMC for what it does compared to other Sphinx in previous MTG sets. It slots well as a beater though since I have many ways to trigger card draw for them, and in a pinch they can be hexproof too.
2x Time Wipe Can help clear the board late game if my Deputy of Detention can't handle it or get removed. On the flip side if I choose a deputy as my target it will release creatures from exile before the wipe triggers and kill them as well. I found in a game if you don't bring back the deputy the wipe kills them before they release the cards, and if not careful you can help the opponent by wiping your side but releasing his creatures back that were previously exiled.
2x Fabled Passage I already have 4x from previous decks, and I have run into mana color issues a few times. Didn't add 4x since I generally get the colors I need with only 2 colors and would prefer my land coming into play untapped if it is early game.
1x Island to fill back up lands from removing Castle Ardenvale
