Tangle Wire is an immensely polar card being a dead draw in the late game and often a Time Stretch against the right sort of deck in the early game
The card cast from Lurrus isn't exiled, so as long as it doesn't get removed from the graveyard through other means, you can always recast any spell you play with Lurrus on your next turn
In a Zombie tribal deck, for example, the player can cast Frantic Search to draw new cards, then discard two Zombie creature cards that they intend to reanimate later
Chaos Wand
This card requires a lot of creatures in hand, but does not require any on board investment (besides mana) or for your opponent to do anything in particular
While the argument can be made that this card isnt quite as intimidating as it used to be, its still an absolute classic that, at the very least, draws attention and forces removal
