When drafting, there is no "enchanter is good into that, engage is good into that", etc., you shouldn't think like that. Pro players would never in a 1000 years say something like that during a draft. Not in a pro game, and definitely not in a SoloQ one.
You see enemy champions, you see your champions, and you determine based on how they all interact with different supports and then pick a champion.
If they have a Zac, Rengar, etc., Poppy becomes an angle. Janna is okay as well, but depends on the enemy bot.
If you're blinding, Bard, Neeko, something that works with the ADC if they're also blinding (which they should if you are too) become angles.
If enemy picks melee support and multiple melees on team, Braum becomes an angle.
If the enemy has an immobile ADC/mid, Leona, Nautilus, etc. become angles.
If you have Jhin as ADC, Karma, Seraphine, and everything else with an easy-to-land slow/CC becomes an angle.
If you have champs who rely on resets such as Viego or Kalista, Renata becomes an angle.
If they have an assassin such as Rengar, Zed, etc. and your hypercary needs something to save them from death, Tahm Kench becomes an angle. Lulu can work, too, depending on the team comp.
If the enemies blind Thresh, Blitzcrank and even Morgana become angles.
If they have nothing to punish you in lane with, Sona, Yuumi, and other weak laners become available.
Alistar is always an angle against engage supports and champs as a stonewaller and great teamfighting tank.
Rakan becomes an angle if your team can take advantage of his teamfighting potential and the enemy bot doesn't have a hard counter like Poppy.
You have too much AD, Brand, Xerath, etc. become angles.
You have Lucian or Corki, Nami becomes a giga angle.
Enemies have champs that can 1v9 and you need something to help your team lock them in, even Camille becomes an angle.
There are hundreds of these that you can think of, and a bunch of them should go through your head as the draft develops.
You might think "they picked enchanter Janna, I should pick engage, YT clip told me engage beats enchanters", and then she QQs every one of your engage attempts and you just end up standing in the bushes the whole lane after dying twice because now you don't know what to do. There are a bunch of things to take into account when drafting, and it can't be dumbed down to "this category of champs beats this category of champs".
Like Soraka is the biggest counter to Pyke, despite the "engage > enchanter" mantra. Nami gaps both Leona and Nautilus if she knows how to bubble their engage, and giga loses if she doesn't. Karma giga gaps Alistar because her W outranges Alistar, and he can never go in. There are hundreds of these that relate to only supp vs supp scenarios, that further influence what champs are good and what aren't as you draft.
If you really want to learn what to pick when and what counters what, it's better to watch Caedrel or some other informative streamer, because I haven't seen an actual good guide on that topic online so far, and generalized rules like "sustain > poke" will just grief you 1/2 of the time because you didn't know how the matchup works.
