How viable is this? I'm pretty new to competitive, but I like Tyrantrum's design and I understand the value of Stealth Rock. I don't think he's that great of a lead, but would it be at all viable for me to run a Focus Sash Klefki, lay down Spikes twice, then switch in Tyrantrum after it dies (and with any luck, with some Screens up) and Stealth Rock?
If it helps at all, my team currently is a Mega Mawile, Salamence, and Protean Greninja. I really don't know where to look right now with regards to completing my team.
Also, would Dragon Tail be a good move to give Tyrantrum after setting up Stealth Rock? I'm wondering whether it might be useful to give it Choice Scarf. Lead with Tyrantrum, Stealth Rock, then switch out to something that can resist whatever moves were about to land on Tyrantrum (maybe even Klefki). Then spam Dragon Tail next time Tyrantrum's out with the Scarf speed for multiple SR procs.
...As I've stated, I'm pretty new to competitive, so feel free to tell me whether this is a terrible idea.
I'm doing the same thing, but with an Aggron. I did use Tyrantrum to breed Stealth Rock onto said Aggron.
What's better/worse about Aggron? I'm hesitant to run yet ANOTHER Steel type on my team, especially as the crux of my team is my Mega Mawile and Klefki already has the exact same typing--a few Earthquakes or Flamethrowers on the enemy team can just totally crush me.
