I bought that trail deck a while ago when i was in middle school to play with friends and went back into the game after high school a few years ago , now my lgs starts doing retro g format tournoments and im thinking about upgrading this to a full deck . Is chronojet g a good vaungard and is time leap good ? ( cause i know gear lists use chronojet z )or should i look to build.another deck ?

Im a returning player and im planning on trying to get the new goblin storm deck from secret lair , im mostly do it for the krenko alt cause he was my first commander but im planning to try and run it as a zada deck , any other cards i should grab for the deck ?
