Eelektross is a pretty good card stat-wise. 140 hp lets you survive zekrom even with a pluspower, 3 retreat makes it searchable with heavy ball. {F} weakenss is bad, no resistance is OK.
Suction heal is pretty subpar, 40 damage for 3 energy. don't use it.
Slurp Shakedown has an awesome name, and could work great in eels decks as a tech against CMT or mirror. free unlimited cathers and damage? yes please. it OHKOs benched celebi primes, and 2HKOs benched eels. It can also work as a tech against truth EX, as you can drag up their vileplumes and kill them to break the lock. It can also be used against durant to kill rotom, but zekrom is better.
Art is pretty nice, but the pose is weird... 8/10
