Its usually played in Commander decks like Hapatra, Vizier of Poisons that make a few snakes along the way to buff your snakes and give you some card draw
This and Dusk Rose Reliquary get better
Cards like Wicked Wolf, Ram Through, Primal Might, and Inscription of Abundance will also help Jorn survive another turn cycle and give us something to do with the extra mana Jorn provides
You can copy big, flashy spells like Crackle with Power, Expropriate, and Aminatou's Augury to throw yourself well ahead of your opponents or lean into the combo side of things
Not only do you have more options in deck building, but Drana and Linvala also has the activated abilities of creatures they control
Finally getting into new cards Bloodthirster is insane
