This should hopefully help bulk out and refine your deck, with a few more powerful cards that arent to be scoffed at
Each Mox card taps to produce 1 mana of a specific color: Mox Pearl White mana Mox Sapphire Blue mana Mox Jet Black mana Mox Ruby Red mana Mox Emerald Green mana The Moxen let you generate mana quickly without using your land drops and play big plays early
Going Blue Taking extra turns lies almost exclusively within the color blue, from game winners like ExpropriateExpropriate and Time StretchTime Stretch to more reasonable, but still powerful effects, like Time WarpTime Warp and Temporal MasteryTemporal Mastery

As long as your commander is on the field, this is a free counter for any non-creature threat
