The basic Alpha, Beta, and Gamma Magnet Warriors are all level 4 Normal monsters. In a Magnet Warrior deck you want to search them out of the deck to use as fuel for other effects or cost to special summon their boss monster Valkyrion the Magnet Warrior.
3 copies of unexpected dai (aka the terminator card? xd). Seems a bit odd to me, dunno if it's worth getting, the only person I've seen playing 3 UDs is gunsblazing. But that guy loves to go against the rules, so u never know if it's going to work or not lol
