You really undererstimate the power of Grass knot. The bulky pokemon which are hit for SE arenīt dangerous but annoying (for example Swampert,Hippo), also a lot of them carry Curse and than they get dangerous.
The Grass/Stab-Elektro/Fire coverage works great with the rest of the team and only Eelektross gets it without Hidden Power. Currently I think about dropping Thunderbolt or Discharge for Thunderwave. Flashcannon isnīt needed I hurt Ice enough with Fire and Ice/Waters with Electric.
Each Rotom form has one disadvantage compared to Eelektross: Either the Sp.A drop (Leaf Storm, Overheat) or Accuracy ( Hydro Pump, Blizzard) and Air Slash just sucks :P
If it still had his Ghost type it would be a great switch in for the Fighting attacks thrown at my starters.
The Genies seem to be great for a the team: Thunderus could eventually work like a less bulkier Zapdos, but of course I have a Jolly one with perfekt SpA and crappy Att IVīs, Landorus similar to Garchomp and Tornadus could hax around with the 100% accurate Hurricane.
Maybe itīs just me, but I only see Zapdos doing the needed job better than the electric eel.
