We now have a lot of fliers. Umbral Mantle gives us ways to do a lot of evasive damage even when we can't make it go infinite. We often can generate a lot of mana with taps and untaps so this can do a lot of damage, so I think its worth a tutor target. And its nice that for one mana Steelshaper's Gift is tutoring up the best finisher for you.
In the sideboard we have tutor targets of Sword of LIght and Shadow and Lightning Greaves to protect your creatures, return creatures from the graveyard (Card advantage) and to give your creatures haste.
Steam Vents is solely for Engineered Explosives being able to hit three counters. But you can also get another color off of some of your mana creatures.
