Black using life to draw cards is going to be the source of some of the strongest cards ever
Haliya, Guided by Light Adding artifacts to trigger the Soul Sister Haliya, Guided by Light is one great thing, but that easy end step trigger is how we know white card draw can keep up with the other colors
In three or more colour decks I am less likely to run the full set, usually one or two tidies up your mana nicely, often one colour has no one drops and so you can afford not to have pain lands over slower options
I've been playing Akiri, Fearless Voyager for years as my own Equipment commander specifically to encourage myself to Go Wide swinging with equipment instead of going Voltron as a self-imposed nerf to the deck and STILL it ends up correct to just pile on all my equipment on to a single creature most of the time
Or something else
You can fairly reliably cast Gweena on turn two in other formats like Pioneer or Explorer, with one mana creatures like Llanowar Elves and Elvish Mystic to help ramp up to bigger cards like Craterhoof Behemoth
