I removed
lightning greaves from a lot of decks that don't really need the haste for a commander's tap ability.
The shroud as protection is useless when I need to target my creatures. And in a world of mass destruction there are better protections to put in that spot.
I'd add
myriad landscape. Not the best ramp but can go in every deck, fix a color eventually, takes 2 lands out of your lib and lands are usually not removed.
