mtg all cards are artifacts Rune of Protection: Lands, Artifacts, Green, Red, Black, Blue, and White from Urza's Saga (1998). Who remembers the old school days of MtG, where janky white decks, the worst color back then Activated abilities of artifacts your opponents control cant be activated Colored artifact - MTG Wiki

Few things say control like taking a player's creature and beating them with it

Planeswalkers have almost exclusively been restricted to activated abilities, have few X-cost loyalty abilities, and almost always follow the pattern of having two usable abilities the turn they enter the battlefield and one they cant (usually the Plus, Minus, Ultimate combo)

Vampire Nocturnus is another great lord, and though it can also jump your creatures into flyers, it requires a slightly tighter decklist and more dedication to play with black cards than maybe youd like to

Void, meanwhile, is a Kicker-esque mechanic that adds extra effect if something happened the turn its card was played

SB cards should be as good as they can be at the thing they are trying to do
