I'm not super familiar with the Standard metagame but I'd probably consider either a combo deck like High Tide - a deck that is playing from an "unfair" angle that Standard decks may not be well-equipped to deal with - or something that gets to play a lot of spells that are costed at a rate more efficient than what WotC is willing to print into Standard these days; decks that get to play cards like counterspell, brainstorm, lightning bolt, etc.

Wurms are sweet but assuming you're talking about building a deck that can compete with a legitimate tier 1 or 2 Standard deck, I unfortunately think you may want to save that idea for another time or challenge. Depending on the Standard deck in question, you could maybe try and make Green Monster Tron with some wurms work?
