Subjective but I think they said it was bad because of the cards he had to discard.

Using they attack itself is not Bad, but they speak about the context. Michael had nothing in his hand, and they Abyss did nothing. So you, not benching anything, and doing only Abyss Seeking yells your opponent that you just bricked, so Using Iono is a instant no. Also, the Game is simplified, rush for they KO and win the game. Ideally in lost box You just wanna be setting up with Flower Selecting and attackikg with Cram, not using Abyss Seeking, that's why it was a bad turn.

If you have to lose abyss seeking and the other guy gets a good setup you are probably going to be behind. It always amazes me to see such an inconsistent deck as LZ Tina get far in tournaments when its so inconsistent, more often than not it seems like you don't get a single card in the LZ before your opponent starts taking prizes

Then why comment?

I mean, you cared enough to say something lol

no one cares about you too buddy
