Let me lend a machete to everyone's intellectual thinking...
1. Steel
- Not only is it chuck full of goodies and all kinds of resistances... but ground always has its way with it... thats why I propose...
2. Ghost
- Thats right, ghost. I hated Metagross in ADV because of its typing... I mean, he was blocking ice beams, rock slides, 4x to psychic, flying, no poison... I mean, the list goes on... steel has proven to be a heck of a type... but (back to metagross) being psychic, it took great hits from ground attacks (EQ) because it didnt levitate. A Ghost/Steel pokemon could stop Lucario from Sword dancing and finishing everthing with close combat, bullet punch is nothing, cruch is neutral (like it would be on metagross), and this ghost/steel beast can fire back with its own attacks... and the list goes on of who IT CAN TAKE ON. No more Earthquakes will bother it, dragon can kiss good bye, and with enough HP, only one weakness, great stats and a big movepool, it would make Brozong look like a little baby. Its simply going to change the Metagame, and thats what we are looking for.
I propose a Levitating Steel/Ghost. Think about this one for a while... I think it would be worth it....
--- As far as redeming Poison... Electric/Poison sounds great although 4x ground can ruin you... a simple Mud Slap could make you your life miserable, but I guess with enough speed, an electric/poison can avoid EQ's enough to fire back with Thunderbolts/Sludge Bombs/ Flamethrower (using Muk's move pool ofcourse)... its a lot more like a sweeper typing anyway... 4x ground, its not good for a Utility/Tank pokemon....
Or, just to keep poison alive, maybe we can meet Nidoking's and Nidoqueen's brother (since I saw a couple of people mention it)... I'd love to see a huge Poison/Ground pokemon take on a whole team like back in Nido's prime RBY...
BUT...
All in all, I stick with Steel/Ghost.
Thats my opinion... PEACE
