so whats your take on string into teleport?
tbh i find it rarely of much use, and when it is, its really hard to execute. of course you can hitconfirm from b12 or the likes, but i personally am too slow to input tele on block and db2 on hit, i always only have one option ready in mind which i will do or not.
that said, the best uses i have found for normal~tele is from pokes, d1 and d3. the timing is really strict though, you gotta press d and1/3 at the exact same moment, and also the up has a certain timing to it - if you do it right it will come out on block and hit though, which is not the case with any other timing (only on hit timing is easier).
f3 into tele is good because it doesnt require any specific timing, just dial it in and you will naturally get it right.
f2, d1 and d3 ~ tele are the only cancels after which the opponent will not switch direction for a reversal but execute it into the initial direction while you appear behind him, so this can be really strong. a slightly delayed poke, maybe just one or 2 frames late might still turn around though and be quick enough to punish you.
