you may play cards from your graveyard mtg Life the Loam If you do What would happen here :

Turning a doomed body into 68 life has saved more games than people admit

Id make sure to include cheap draw spells, like Frantic Search, Faithful Mending, and Meeting of Minds, to trigger our card effects on other players turns

There are a few at various levels of damage that target both creatures and players, which can maximize your triggers in a burn deck

Whenever Chaos ensues, put a flying counter on up to one target creature

Spells like Nadir Kraken and The Locust God that create tokens as you draw cards are great ways to defend the crown while Psychosis Crawler and Niv-Mizzet, Parun turn the card draw into pressure to wrap the game up

With so many good instants available, once a player untapped with a Shadowmage Infiltrator and an otherwise empty board the game was practically over, and if there was some small threat left over it could be dealt with in due time
