With very many Magnezone cards that we have, it is sad that not many Magnezone decks run around at the moment. I guess the format is really not friendly with the floating magnet. This Magnezone, in particular, stands out as it can be a great main attacker if set-up right.
HP of 130 is normal for a Stage 2 these days and expect it to last a turn or two. Weakness to fighting is bad with Machamp (SF), resistance to Metal is helpful (but not overly useful since there are not may Metal decks around), and retreat cost of 2 is somewhat nice for a Magnezone, although still quite expensive.
Charge Beam is a nice attack if you don't have enough energy attached to it. Although with the damage output, you should better be relying on the second attack as your main attack. Metallic Bolt is bad since it does 60 for 4. However, if you discard a Lightning and a Metal energy, it goes up to 120, which is great. Another great thing is, it is not mandatory to discard anything. If you feel that the Defending Pokemonc can be KO'd by only 60 damage, you can get away with not setting yourself back a few turns of energy attachment.
Theoretically, you can do 120 damage per turn using Metallic Bolt, and with all the other resources Magnezone has at its disposal, it is not that difficult to do. Having a Magnezone (SF) with Super Connectivity on your bench can let you attach an energy from the discard and with Conductive Quarry, you can flip for a heads, and attach another energy for Magnezone, enough for another use of Metallic Bolt. However, if you don't want the flippiness of the Stadium, you can get have another SF Magnezone on your Bench, although that may be clunky. Adding Electivire (SW) can be good with Magnezone LV. X to move energies around. It may be good to tech in a Nidoqueen (RR) just to offset the drawback of Super Connectivity.
No doubt that Magnezone decks are fun to use with the many options available. However, the deck is just too slow and disruption in the form of Bright Look can instantly ruin your set-up. Nevertheless, this Magnezone is one of the best as the precursor to the Level X.
Modified- 7.5/10 (good attacks and fun to use with other Magnezones, although too slow for the format)
Limited- 0/10 (promo...)
