Abomination

not sure if you want this as standard legal, if not you could always use rune-scarred demon to get your immortal servitude.

Gomazoa or void stalker would help you with creature based decks they clog up the battle field and they shuffle your opponents deck and your deck so your trickster gets two activation's

Did you ever consider adaptive automaton? it even turns into a troll itself.

I like this deck, my wife runs something very similar to this and its nasty to play against.

thanks for the likes and comments

why would I do that counts as a locus

thanks for the comment glad you like it.

I like the deck, I would try it with a couple of copies of gravepact and dark ritual.
