That's because by design link monsters cannot change their battle position. They have no level either, so Wightprincess does not work on them. You can still use it on monster that (you know) is about to be used as link material just like you would interrupt Synchro by floodgating the tuner.

I really wish all cards are 1 liners such as these.

it's not always convenient. For example, Pot of Greed tells us to draw 2 cards. It is difficult to draw when we don't bring pencil/pen/crayon with us.

Floodgate is better

Lol no. BoM is better than FTH because BoM is a Spell and its effect can be used anytime, meaning it can quickly respond to threats, even threats that are already on the field.
Literally every deck runs 3 copies of it, hopefully they limit it soon.

I have 3 variants of Superheavy Samurai deck and none of them runs this card.
I was using subterror deck and my opponent used this card it didn't go as he wished

Released in a good box.
The box cover is not even playable, though.

I tested and it works as intended, there wasn't a single glitch or bug with card, could it be a skill or something?

It’s useless against Links tho, although the latter isn’t here yet.
Once this card is released in a box, it will be a bad main box with book of moon being only the good card.

it didn't, the box was rather quite decent.

That blizzard spell card is truly trash filler for a UR spot in a main 4kn box, whoever made that decision deserves lethal injection.

The problem with Blizzard spell card is not that its that thrash like everyone say, it can win you a turn, which is often enough to turn the duel for your favor, but yeah its a tech card right now and not worth a pernament sloth, maybe if we had side decks, then it would be a good side deck card.
