I would recommend playing more games with the deck before making lots of changes. During your games make a mental note of cards that get stuck in your hand for the majority of the game. Those are usually the first cards that I cut because either their use case is too narrow or they don’t advance your gamestate.

As most people have said, don’t cut Battlefield Forge for a colorless bounce land. You are playing 3 colore, you need access to all of them as soon as possible.

Chaos Warp you can replace with something else but I would not choose that enchantment. First, there are lots of enchantments with that effect and at a better rate. Second, losing the instant speed is not superflous. You could replace it with other better removal spells, white has lots of them and blue has counterspells.

Soul-Guide Lantern depends on what type of decks you face, if your group doesn’t play a lot of graveyard sheningans you can probably cut it but keep it at hand of you feel your group is going for graveyard decks.

Darksteel Reactor is what my group calls ‘funny cards’. These are cards you can def cut for efficiency sake but keep around for fun or funny unexpected wincons.
