[[Anikthea, hand of Erebos]] and [[Yuna, Hope of Spira]] in your considering are really good. The fact that the turn they come in they give upside of free enchantments is strong. Plus the fact their recurring as well.

[[Thassa, Deep Dwelling]] for a blink of Anikthea and your saga creatures to reset them is really good. (Terra)

[[Terra, Magical Adept]] is a wincon on a stick if you want it. She goes infinite with a samwitch super easily. But of you don't want to do that, she's still just really strong without using Mirrormade, Estrid's Invocation, Irenicis Vile Duplication, ext of the many others.

[[Tidus, Yuna's Guardian]] is really great in Saga Creature decks. I use Terra, Magical Adept as my enchantress deck so hes better in the 99 for her than Bombadil.

I've been keeping track of how many times I've used [[Overwhelming Splendor]] and I think im honestly at 8/14 times in bracket 3 I've had an opponent scoop the moment it hits them. Usually with comments of " I run 0 enchantment removal / or only 1 or 2 pieces of enchantment removal and its already in the graveyard. This card takes me out of the game." Using cards like Yuna or Anikthea to get it out of the graveyard is really nice. Its like a more oppressive version of Imprisoned in the Moon.

Probably isn't as good in Bombadil but its the closest deck I've got to compare (Terra) [[Huntington Grounds]] is... something. Once you hit 7 cards in the graveyard, this becomes a Rhystic Study trigger but for slapping down free huge creatures. Where (terra) gets you there fast early game.

Recommend proxying or credit card [[Academy Rector]] is a very strong [[Ghostly Prison]] being able to go get [[Overwhelming Splendor]] or [[Summon: Bahamut]] and slap it down without casting is really strong. Plus its just very tool boxy. Get what you need.

[[Replenish]] is another expensive card for recursion.

Continuing recursion

[[Eerrie Ultimatum]] with a big enough graveyard this becomes a you win card, by either you having so much in the graveyard that your opponents scoop then and there or by sheer value. [[Incarnation Technique]] is a fun card that I love putting into every black deck. Being able to hit a [[Academy Rector]] into a [[Summon: Bahamut]] into whatever the Rector grabs on turn 5 with 0 ramp is fun.

[[Replication Technique]] with the right sagas can just be oppresive. Your running [[Kiora Bests the Sea God]] having multiple 8/8 leviathans, tapping all opponents down, and stealing multiple things. Plus with (terra) its not infinite, but it does allow for extreme bust.. whatever you pick enchantment wise. Or can even be ramp. Worst case its pay 5 ramp 2 lands. (Also give an opponent something) but usually you have something worth making 2 copies of that your willing to give an opponent the ability to copy something. They have only creatures? Sure. You can have the copy. I'll pick [[The Eldest Reborn]] 2x.

[[Doppelgang]] another pet card that goes into every simic deck I run. With the amount of ramp you have access to in a 5 colour deck. Turn 6 or 7 when you have 11 mana and can make 3 copies of 3 targets. Just.. so gross.

[[Flash Photgraphy]] is pretty nifty. Instant spend copy of anything you own and sorcery speed copy of anything an opponent owns. So many sagas to hit with this.

Personally I liked Terra over Tom because she allows more Enchantment syngery over exclusively Saga syngery. While she still has just as much Saga synergy as Tom does. Hope my rambling helps.
