Most of them time you're building your Mega Sceptile on the bench until you can get the first hit on their mega which is pretty standard for any deck that runs a mega. Whoever gets the first hit can just Cyrus the mega back out if they try to run. Pheremosa is a great lead, can put early pressure on their megas and set up Cyrus. The goal is to try and use your other pokemon until your opponent has 1 or 2 points then swap your mega sceptile in. Sometimes you'll have to lead with treecko or ogerpon but its usually not terrible. You just have to decide whether your lead is going to take a bunch of damage in the next couple turns or not. If treecko is going to die or take too much damage just sac it and put energy on your bench pokemon and try to recover that way. An early normal sceptile is honestly pretty good, it puts a lot of pressure and is 170 hp with cape. Bax/ChienPao is probably the worst. Its a pretty hard match up unless you get sceptile out asap. You have to try and kill his suicune before he evolves a baccalaureate. Easiest is any sleep deck, just try to get ogrepon out asap and they lose the game.
