Dracoslayer Metalfoes Trinity format edition

Similar to the deck I recently posted, but I wanted to try out trinity and this deck seemed neat. The goal is to turbo out master peace (the one that's not banned), or to just spam cards as much as you can with only using three effect monsters.

for reference the cards I used points on were: an extra copy of box, a copy of diagram, and an extra copy of goldriver

Any and all feedback would be very helpful seeing as this is my first attempt at a trinity deck.

edit: didn't realize terraforming was co forbidden, replaced it with metaverse.
