You dont have to keep track of exactly which card came from what pack, but I recommend recreating packs with the appropriate ratio of commons, uncommons, and rares/mythics
With vigilance, shell dish out the punishment and still be there to protect your face
Kang doesn't need to have been under your control when the first card is drawn for his last ability to trigger
I debated putting this one on the list because it is no doubt a beautiful card, but it also doesnt go into uncharted territory like many Floodborn cards do
So it has added value, but at 4 mana, its one of the most reliable card drawing spells, for no additional mana or costs, youll find in the artifact kingdom
Making board wipes cost more mana is a way that white can gain card advantage and keep its board, and whether thats in constructed or in Commander, its a valuable ability
