jiggs is definably a match of patience. And don't be ashamed you lost to a jiggs. Its the player that matters, not character. But you can kill jiggs after 3-5 hits. and well, jiggs attacks from usually the sides, meaning if you can really predict jiggs well, a forward smash can send her flying to death at 40%. Otherwise you'll have to get her to 70~80% for a usmash/utilt/uair/ftilt
Jiggs have a dair > rest combo to watch for. Rest is still strong so it'll kill you by 80~90%. So, its a battle on who can get the other person to killing % first. You have the advantage here since your attacks kill cause more damage and since Jiggs is hit and fly tactic, she'll be doing one WoP then retreat. Well, if you can do well enough, you'll avoid it or get hit only 1-2 times there by taking less damage then what you inflict on jiggs. But you both have ways of destroying each other at earlier percents. You with a forward smash and spike, and her with a WoP of the stage sending you too far to recover.
Jiggs has a 2nd move that kills, rollout. This is a mind game kill, you have two options for this. If you can do this well, you can counter this. BUT, jiggs can change directions 3 times. She can bait you to counter then strike and kill you. Jiggs normally will do rollout recovering to the stage. When it comes to FD, you HAVE to jump/dodge/counter it. Any other stage, you have a platform to jump to or stay on so you don't risk getting hit and missing counter. THE WORST CASE THAT CAN HAPPEN IS: you counter and rollout goes THRU you, then your ****ed when jiggs changes directions. BTW you can outrange it and hit jiggs out of it, buts its not recommended if you are new to it.
Here is what i do to handle jiggs. I gound stalk her. Cause, well, stalling is banned normally, so jiggs WILL have to come down eventually since you can't reach her. Ground stalk and prepare to counter attack what she throws at you, whether you use retreating fair/utilt/usmash/angled up ftilt/nair is up to you. jiggs will always be in the air, so, you won't be using jab that much. Heck, this battle will all be, fair, nair, usmash, utilt, uair and the bair. Jab will come out every now and then cause jiggs does have to land, but you won't be using jab too much if you play right. You'll be just hitting jiggs to far away. utilt and bair are you best kill moves. Uair is a bit hard to pull off, but if you do it'll kill. Usmash has post lag jiggs can take advantage of and it's slowerShort hop bair will do well to hit jiggs away from you, but don't miss with it now
Best stage is a low ceiling stage. Like Halberd, and STAY THE HECK AWAY FROM JUNGLE JAPES
well back to my vacation now,
