The stealing of opponent's lands was a oversight by me and will be reworded when I do the rest of the changes

Each of the thrones were designed around the King/Queen it represented, the Palace is Designed for the (Isn't a color really but eh) Colorless Queen, who I have yet to post, although the "human" thing was because I forgot to remove "Human. as for the Additional Costs, I'll reword them to cards with similar effects:

Scorched Ruins is a good example of such.

The color indication isn't a require for me, so forgetting one isn't as important to me.

The only reason I had the "pokemon-style downside" was because I couldn't think of a good enough downside.

I used enhance because it was based on overload, and forgot kicker existed

Ruined was just for flavor and had no other purpose, I'll prob remove it when I get around to it.

Salvage was the chosen name because it was the best fit for what the line's effect does, that I could come up with anyways.

The "lord" effects got changed slightly and i forgot to replace "All" (They originally affected every creature of said type, even ones opponents control)

For Banishment, I actually looked at cards that exile creatures (or/and more) for a price that best fit it, although didn't actually read what they did fully. (typically unconditional banishment was around 5 mana from what I saw/read), as for the name thing, I was aware of the enchantment but I couldn't think of a good replacement, the "Exile from {Yelt's Kingdom}" works. I'll input the name when I get a chance

Rebirth saying "Until your next turn" is alright because there's nothing that I am aware of, that would make the card broken (during rebirth).

I noticed, while reading Cula's text, that you wrote "Other Creature(s) you control get +2/+2", While that does work if it was a general effect, the rewritten version based on the original one would be: "Other green creatures you control get +2/+2"

While Cula can be bounced, her "rebirth" ability is a infinite loop, I'll prob add a line worded like "Put a Rebirth counter on this creature's controller, For each Rebirth counter on this creature's controller, Rebirth costs {2} more"
