Coaches - even evil ones - can't repeatedly use the same "play" because the other team quickly learns how to counter it. Rather, they use a variety of "plays" to win games. 'Same with the DS/swamp -- they may be evil but they're not stupid (AND they're literally "playing to win to save their lives"). As such, they'll use a the intelligence, cunning and strategic-thinking they can muster to formulate and implement numerous "plays" to "win the game".

Since the 2020 election, lawfare (at various levels - alternate electors, canvassers, election officials like Tina peters, J6ers, Tweeters [AlphaWarrior], podcasters [Alex Jones?] and PDJT) and assassinations (Lamb's family members(?), Kemp's daughter's boyfriend and the investigator looking into it) and assassination attempts (PDJT) have been some of the more obvious "plays" to mess with elections by scaring/terrorizing, bankrupting, compromising and distracting people and to shut down disclosure/whistleblowing, opposition and investigation - for past, current and future elections. And, in all likelihood, they will try more novel "plays" in 2024.
