A basic run down of Dante’s gameplan from Mecurial, a Dante player who’s put a lot of research into the character. Since you’re using XF3 Dante, this applies.
*XF3 Dante is an entirely different character than Non-XF Dante.
Non-XF Solo Dante is difficult to use well. His safer solo tools vary by matchup, but basic options like jS xx Hammer / Stinger( xx BC Specials) / Reverb xx Fireworks / Hysteric / Airplay / jM / jH / sM are all good. Dante’s basic gameplan is to play safely, with mid-ranged pokes and projectiles from midscreen, until he can put the enemy in blockstun/hitstun and safely go in closer for things like teleports and airdash normals. The hits you should be going for as Non-XF Dante to start a combo most often, are jM / jH on grounded opponents(often as a crossup after an airdash over them or teleport), Stinger from ~mid range, jS from anywhere you can hit them with it safely, Hammer(if they block jS or you think the positioning is right), and sometimes sM/sH as anti-airs. Vortex makes an appearance here too, now and then
XF3 Dante is about all those things, done twice as fast, with a lot more usage of Devil Trigger and air mobility. He’s free to do things in Devil trigger much more often, because he can kill without meter and he can build a lot more meter during combos. XF3 Dante’s neutral game uses a lot more projectiles, like Hysteric and Drive and Multi Lock, because the opponent is usually trying to get away, and they make it safer to teleport in on them. XF3 Dante’s neutral game uses a lot more air normals, because while it’s always comparatively easy to land a hit with them, in XF3 Dante has a much easier time of turning them into a combo, by chaining into jS. jMHS works, jM xx Doublejump.jHS works, jH xx Airplay -> Airdash jHS works, etc. The focus should almost always be getting into the right position to hit the jHS link and get them to the ground, for his touch of death combos. Likewise, you need to be good with your mixups on incoming characters, and movement, with XF3 Dante, because once you touch a character and kill them, you want that to lead into killing their other characters before they can jump away and make you catch them again.
Dante is definitely one of the more difficult characters to use very well. Yipes is a good example of a character to look at for how to play non-XF Dante.*
Said Dante player also came up with these XF3 combos: http://www.youtube.com/watch?v=skpyi1wJv2o&list=FL4KunoV3DEuliyPTr2ZMyMg&index=2
I’d strongly recommend Weasel Shot in certain cases where you’re desperate for a get-in/pinning assist when using Trish and Dante together. You’ll sacrifice your Jam Session lockdown, but I really dislike Low Voltage, especially against chars with strong projectiles that can negate Low Voltage’s start-up. Then again, Weasel’s shot’s not much better in that regard either, it just starts up way faster (but has other issues).
For those who want to pair up RR and Ammy with X-23 together (which isn’t many lol), you can TAC past RR in 2nd to Ammy in 3rd when extending combos with Log Trap (Pendulum) and hit people with Ammy’s TAC infinite. When X-23 dies, RR will have a good assist to back him up, if he doesn’t get nailed by an incoming set up that is. Not sure if you can do Ammy’s infinite midscreen, but if it’s corner only, that’s one other reason to TAC past RR to her with Log Trap, as the combo will corner carry them from anywhere. Your combo has to be very short however, which is annoying. I heard RR and Cold Star work fantastically, and Cold Star is a great assist for X-23 too, as people know.
I’ll try and do some more research into RR+Ammy with X-23. An interesting idea could be to do an X-23 version of the "tech-community challenge thread, post up teams and research into them for a month (a new thread wouldn’t be necessary though, just post the info here.
Also, at some point, I’ll have to go and filter all the information in this thread. BTW, does anyone know how to fix your avatar image quality haha? Do most/all avatars have to be at 100x100 and under to avoid them looking like vomit, or use premium? Or do you just have to get lucky?
