well, no, you don't have to play a game to get Magnezone. He is in the Cavern Zone, usally floating around the wood-splattered wall with signs and arrows. He is near Cranidaos and Electabuzz. Or maybe one of those bats.
Run around the zone, breaking every single crate you see (Except the ones behind Marowak) and when you find all three Magnemite, Magnezone will be around Dugtrio near the entrance to the lava zone
You will need to first catch Magnemite or Magneton, Magnemite is available in the Virbank Complex in Pokémon Black 2 while Magneton is available near the P2 Lab... provided you catch a Magnemite instead of a Magneton then you will first have to evolve it to Magneton and it will start to attempt the process at Level 30 and then you will be able to take your Magneton anywhere in Chargestone Cave and all you will need to do is level it up and it will evolve into Magnezone.
If you level up Magneton in Chargestone Cave, it will evolve into Magnezone.
magnezone: get all three magnemites, found in crates in the cavern zone, then the magnezone will appear.
Magnezone is in the cavern zone near dugtrio, and he battles you. You have to find all three magnemites to make him come. The magnemites are all in boxes scattered around.
When you are far into the game, you will see Lavana with a Magmortar and you will have to capture it.
Magnezone is an Electric and Steel type pokemon.
To get a magnezone you have to level your magneton up on mount coronet
You cannot evolve magnezone, but you can evolve magnetite into a magneton at LV 30 and evolve the magneton into a magnezone by leveling up magneton in Mount Coronet
they are both metal types wich is good. they are both last evaluation which is also good. but magnezone is also electric so go with magnezone
