When you're sick there isn't much to do. Only cards from Ex Ruby & Sapphire, Ex Sandstorm, Ex Dragon, and Ex Team Magma vs Team Aqua allowed. However, energy from previous sets are also allowed.
x3 Mareep (Dragon)-It has resistance to Steel. Needed for evolution.
x2 Flaffy (Dragon)-Resistance to Steel. Needed for evolution.
x1 Ampharos ex (Dragon)-Wow! Conductivity is a nice ability, doing damage to the foe when they place an energy on their Pokemon. Free damage is always nice. Gigavolt is an amazing attack. For three energy it either does 70 damage or it does 40 damage and paralyzes. Either one is great. To top it all off, it has resistance to Steel and 150 HP, making the two prizes obtained when defeated so much harder to get.
x3 Magnemite (Thundershock) (Dragon)-Thundershock is a decent one for 10 with a chance to paralyze. Needed for evolution.
x2 Magneton (Magnetic Field) (Dragon)-Magnetic Field is a good ability. I discard an energy and get back two, then can get that one back the next turn. Magnetic Force can do a lot also. For two energy it does 20 damage (due to me having two energy needed to use the attack) and then 10 more damage for each energy on the rest of my Pokemon. Resistance to Steel is also a nice bonus.
x3 Spearow (Sandstorm)-Resistant to Fighting. Needed for evolution.
x2 Fearow (Sandstorm)-Its attacks aren't the best, but a three for 50 colorless attack is decent. The main point of Fearow is that Fighting resistance. Colorless Fighting resistance cards have always been a part of Electric decks (except when Rocket's Zapdos came in and provided a great Electric type card resistant to Fighting.) No retreat cost is also nice.
x4 Electabuzz (Sandstorm)-A 60 HP basic with Steel resistance. Plasma is decent, a one for 10 with a chance of getting an energy from the discard pile. Thunder Spear can be a decent bench damager.
x4 PokeNav (R&S)-Gets me a card and lets me control my drawing.
x4 TV Reporter (Dragon)-Drawing. The card discarded will usually be an energy that Magneton can just get back.
x4 Warp Point (MvA)-A Switch and a Gust of Wind rolled into one.
x4 Energy Removal 2 (R&S)-While I hate the coin flip, this card can be useful with Ampharos, forcing the opponent to place more energy and thus damaging their Pokemon.
x2 Professor Birch (R&S)-Drawing.
x1 Low Pressure System (Dragon)-Adds 10 more HP to my Electric types while also removing any Stadium card my opponent has in play.
x17 Electric Energy-Needed.
x4 Double Colorless Energy (Base)-Mainly for use with Fearow, although Ampharos and Electabuzz can make use of them.
This deck hits hard with Ampharos ex. Magneton supplies me with a constant source of energy, while my opponent gets damaged by their energy.
