I can't believe this hasn't started yet.
Toon's ledge options.... where to begin...
If I'm returning on stage I will generally use the ledge hop or the double jump back on stage. These are mixed up with attacks or airdodges. Toon's other options such as doing a ledge attack, returning with a bomb, rolling etc, all involve actually returning to the stage. But this is only half the story. Has anyone ever considered simply not returning to stage as a legitimate option? You see, if one of your mix ups is not going on stage, then the options that involve actually getting on stage will become less predictable and will work more often. This isn't just theory craft, this actually works for me.
So what do I mean by not going on stage? One option that will no doubt come to mind for most of you will be the re-tether. This option imo, doesn't seem to be as effective simply because it's over quite quickly and you only have three of them. This is because essentially, what you're trying to do when you use the options that don't go on stage is either bait a response or get them off their guard for when you do actually return to stage. Other options that might come to mind are pulling out a bomb then going back on the ledge or hitting away from the edge throwing a boomerang then returning to the edge. Again, these options aren't that great because it makes you vulnerable because when you're bomb pulling or boomerang throwing, you are left with no options and a lot of lag. So what else could I be suggesting? It's simple, a little too simple. You hit away from the edge when you still have invincibility, drop for a bit doing nothing, then at the right time, you double jump back towards the lip of the stage and auto snap on to the ledge from the maximum distance below the ledge. I know right? But just hear me out.
The reason why this works is because it leaves you with many more options compared to the bomb pull or rang toss for example and it's the perfect bait. Not only that, but it's surprisingly safe if you space it correctly. Opponents won't be able to hit you from the stage even if they are right on the edge. You'd be surprised how far away from the edge you can be and still snap on. Now I know what you're thinking, but this idea is just begging for a stage spike or any other type of spike for that matter. Exactly. People are more than likely to try and go off stage and hit you somehow. So what's the plan? If you do try this too many times and they do fall for the bait, you can double jump early quite easily on reaction and airdodge on-stage. Or, you can double jump U-air them, keeping in mind that our U-air beats almost every Dair in the game (except for like Lucario and on some angles Link). Or, you can double jump and stall the timing of your recovery with a tether (depending on the character, this has worked for me). They edgehog? Uair will beat it. They wait for you to double jump then try to hit you? Uair will still work or you can airdodge the attack (to tether) or you can stop your double jump with the tether. It's not actually that hard. Now I'm not suggesting that you tempt fate every time and simply wait for them to respond, that's where the other side of it comes in. Not returning not only baits responses, but it also puts them off their guard for any other options. If you've done one or two of these, an attack is more likely to hit them and a ledgehop is more likely to not be punished.
If you can bait a response, Toon has the tools to turn the situation around and you'll find yourself doing the edge guarding. If you throw in one of these every now and then and they don't take the bait, your other options are more likely to work and you'll get back on stage just fine.
I can't explain everything and there's no doubt in my mind that I've missed something (try to fill in the obvious gaps for yourselves), but if there are any questions, just ask. Give it a go in some friendlies, if it doesn't work for you, then don't use it. It works for me, that's all I'm saying. You've heard it before, don't be predictable, and that goes for this too. Use every option you have even if it means not going back on stage.
Maybe others will have better ideas. If you think you do, please share.
