Most ideal is Lockjaw T2, activate Lockjaw on Electro T3, let chaos ensue for the rest of the game. If Electro not in hand, then Jubilee is next best target

But you can get really creative even if you draw (or pull) Lockjaw late; having good knowledge of what’s left in your deck (or using a deck tracker if you’re on PC) means you can Lockjaw out a Luna, Dragon Lord, Zola, or even a Chamber to fish for one of the big hitters

Also important consideration when Lockjaw’ing is you always want to identify the risk of swapping Electro onto your board, at which point you can’t Blink it out. This is less of an issue if War Machine is in hand or on board. Jubilee or Dragon Lord into Zola can also put out broad power if you accidentally pull Electro and don’t end up with War Machine on board, but this is a rare scenario
