Grabbing a creature like Gishath, Sun's Avatar from your deck and putting it into play to quickly overwhelm the board
Travis King has a great video on the topic over on Youtube
Weekly digests, tales from the communities you love, and more Cards like Tenuous Truce and Baird, Steward of Argive keep opponents from swinging at you and the likes of Bloodrot Apothecary (which pings enemies with toxic damage for each token they sacrifice) can literally kill people with kindness
You can protect key synergy creatures you have, protect your commander, sweep the board, and have them all return to the battlefield safely, while your opponents return to ground zero
Then you get a 3/4 body, but you can cast one critter from your graveyard each turn like Chainer above, but you don't have to discard anything
