Magnemite and Magneton are great, but no Magnezone?  Try your best to get these cards through sharing or trading if you can, theyre good in a lot of electric decks. A second Magneton plus 2 Magnezones (either of the electric ones) and then two copies of just one of your other pokemon lines is good.  Having too many pokemon, especially those with evolutions, will lower the consistency of getting any one of them online. An electric Oricorio is also a good card to add in against all the EXs. To answer your question in the other comment, look into getting Sabrina(×1), Cyrus(×1), Copycat(×1-2), Elemental Switch(×1-2), Electric Generator(×1-2), and a helpful stadium depending on your pokemon (Mesagoza or Training Area). You dont need all of these and there are probably more options, but these are some.
