Ok, this trick is simple, first, u need the DangerRing, and the CardFindr. and a few cloakers and Searcheye.

Ok, if u need a V2 card. heres my tip. just go all out, make sure its BEFORE u face MeteorG, theres a glitch fi u faced the V2 in there, u cant meet them int eh locations.

Ok the trick on gettign easy V3 cards are.... Search for the V# witht he dangerRing plus cloaker.(make sit shorter and less time to waste) then, run from the V3 u need to face. after that. Change the mega's weapon and use the search eye. Oh! save after u doen all that. incase u get deleted at least. Tehn keep searching. and there u go. u can try this as many times u need it. Happy Hunting XD
