A good starting point for many Commander decks is: Around 3638 lands Around 812 ramp cards (Such as the Talismans, Sol Ring, Arcane Signet etc.) Around 812 card-draw or card-advantage cards Around 812 removal or interaction spells These numbers are not strict rules
While the imagery is legendary, the card choice is quite bizarre
Crib Swap is just a weaker Stroke of Midnight, with the benefit of having the Changeling ability
Visions Visions the spell, not the set gives you knowledge on the top 5 cards of any player and you can choose to shuffle that players library after
Invasion of New PhyrexiaInvasion of New Phyrexia Well, well, well, looks like the tables have turned, taking the fight to the invaders' home plane
Let me know what you think of my recommendations and if you have any of your own
