This is my personal favorite deck and what I use for most paper magic events so I just can't help but share it here. Comments are welcome, enjoy!
Ancient Tomb, City of Traitors, Cloudpost,
Glimmerpost
, Vesuva- These are our lands that we use to accelerate our mana, Notice each of them either provides more than one mana or is part of a whole to provide extra mana.
Cavern of Souls- Sometimes you need that extra assurance that you're plan will happen, and an uncounterable Metalworker is a step in the right direction.
Wasteland
- With our lock pieces snuffing out lands is a great idea. Say they have three lands and you have a Trinisphere, lock them out of the game! Or maybe a Maze of Ith is in your way, waste it! Abrupt Decay scaring your [[Metalworker? Blow up their Bayou!
Wurmcoil Engine- Nice cmc, efficient beater, and takes alot of work to get rid of.
Spine of Ish Sah- Gets rid of problematic permanents, is forgeable, and is great to bring to show and tell.
Grim Monolith- Turn 1 Metalworker or Trinisphere is very good.
Chalice of the Void- We want it to nullify early plays and make them move slower. Also keeps Swords to Plowshares off of our bigger guys.
Trinisphere- Same as above, slows them down and can completely nullify some strategies. Comes out turn one off of a Grim Monolith.
Lodestone Golem- Taxes our opponents spells.
Kuldotha Forgemaster
- Helps us get out those harder to cast creatures. Ranges from anything like a Platinum Emperion to a Blightsteel Colossus for the finish.
Metalworker- Comes out turn one thanks to Grim Monolith and helps power out our larger spells.
Steel Hellkite- A good, evasive beater that can clear the board of unwanted permanents and can be pumped with our access to abundant colorless mana.
Uba Mask
- Great against decks with reactive cards and Brainstorm.
Blightsteel Colossus- A major win condition, can steal games out of nowhere. Usually fetched with a forgemaster.
Sundering Titan
- Helps us deny them mana while being a huge threat. Really punishes the three color decks.
Please leave any suggestions, I would appreciate it.
