Darkrai EX and Weavile EX

Darkrai EX and Weavile EX have a lot of synergy. The former can sit on the bench and set up while dealing damage, making way for Weavile EX to come in early and start mowing the lawn. Rocky Helmet also helps with chip damage. Spiritomb may seem like a slightly odd pick here, but it serves two purposes: first is as an early-game wall with a low retreat cost. If you put a Giant Cape on it, then it reaches the coveted 100 HP benchmark, allowing it to survive at least one attack before dropping against the majority of decks. it also hits the entire bench for 10 damage, which opens the field for Weavile EX to hit for maximum damage, and for Cyrus to pull in any card at will.
