So the way this deck came together was mostly born from my desire to put together an effective Chromanticore deck. However, the correction and fetch involved with making it took up so much deck space and mana that it is very hard to also develop a controlling board. So, I decided that it was more effective to just make a board that can grow itself, and one that can really let the Bromanticore shine.

Why tron? Well, Chromatic Lantern, Expedition Map and Paradise Mantle are all colorless, all playable in the early game, and are all important parts of the deck anyway, so having only colorless mana in the beginning is feasible. Plus, once the Lantern comes down, they are all usable as any color anyway, and the extra mana can really help with some of the higher costs.

The other lands are to hit important early colored drops, such as Noble Hierarch for mana correction or Fabricate to fetch an artifact.

Captain's Claws builds board, Raise the Alarm gives you targets for early game equipment. Argentum Armor goes on your finisher. Everything else is to build Exalted damage, so that your swings are threatening even if you only have little creatures, and also to make your Bromanticore into a massive creature.
