All things considered, Chocobo Racetrack is rather clunky, and if you dont have extra Lands ready to go, the card essentially does nothing
This Esper deck combines the card advantage afforded by Blue with the control offerings of White and Black
At just one Ink for her Boost , it could be worth paying straight away for the Foil Megara Secret Keepers ability
Soft board wipes are more situational , usually because they impose a limit on the creatures they remove
You dont need anything else to play them with friends or family
