you can still do fundamental pressure efficiently, such as shine grabs. However, if you slip on the timing, yeah you can get grabbed outta shine in this game. Like, not phantomed, but fully grabbed with the armor of a grab. You can still pressure people with the shine, and if they mistime their grab as well, they can still get hit by the shine if they are more than likely just spamming it. So, your pressure is a lot more of taking advantage of different situations that can lead off of stray hits, from like bair or nair shine, then getting the up throw up air, or whatever you can manage. Shine gimps are more match up based on how efficient they are because some characters have better recoveries, and the knockback on shine is changed as well. so you pretty much have to go off on a real bait and punish type of game as far as how you'll be utilizing pressure. Not too different from melee fox, but you have to be either completely efficient with your pressure, or completely thorough with your punishes. Ideally, you want both, as basic as that sounds, but spacies are among the characters that are a little more subject to this than some because of their weight, and almost given punish games that other characters have on em.
