With a quick once over the changes I've made are -

Cuts -

Jalira, Master Polymorphist (Stuck the Foil to command my Guile 2HG deck)

Scuttlemutt

top (prioritized including this the first time round as i had just pulled a Foil from an EMA draft. Often felt I was drawing more than enough and generating enough mana to not need it, and my league plays with a bounty...)

Bident of Thassa.

I honestly can't remember if I cut the whole devotion suite or not (Chainer, Gary, Abhorrent Overlord)

Additions -Mystic Remoramirror matchMeta dependent cards I have to keep otherwise would potentially cut:Thada AdelBile Blight Faerie Artisans although its quickly becoming a pet card of mineChopping block --Dictate of ErebosHalimar DepthsBeguiler of WillsSifter of Skulls / Pawn of Ulamog

Future things I want to test/Acquire:Glen Elendra Archmage - because why not? built in recursionKheru Bloodsucker -doing +2/-2 swings sounds good but my deck mostly spews tokens for fodder..Kalitas - a recommendation from a lot of people that i don't want to $ in to testHavengul LichDeceiver Exarch - not sure i have enough payoffsParadoxical Outcome - different kind of finisher than usualGonti - having the smallest budget in my meta makes me want to play their stuffYahenni (high on my list, free sac outlet and grows?)Phyrexian Altar - the deck sometimes gets very color hungry but that may have been Chainer, i don't remember it being a problem recentlyPhyrexian TowerPhyrexian MetamorphBitterblossomCloudstone CurioTorrential GearhulkLandbase - but who doesnt want to upgrade theirs?Soldevi Adnate (unsure about this one, another recommendation that I've seen be used to great effect, not a fan of the cardframe though)Sire of StagnationNot sure if you noticed but 99% of those would increase my already high curve...New ways to Take it that have come up that would require a lot more workPlanewalker suite (but i'm broke)Discard package (more likely)Things I loved testing but didnt stick aroundDay of the Dragons -- it was awesome to pull off but super mana intensive and only Vela triggers on the creatures going to ExileWash Out - feels bad...Butcher of Malakir - expensive redundancyBlade of the Bloodchief - back to my voltron thrax deck
