Why does this card see no play anymore?

Back in the A1 set, this card was an absolute menace. Most players were annoyed and called this card ‘problematic’ for how immediately offensive this card is. If given the second turn advantage, this thing can easily win the game by Turn 4.

The 0 retreat cost, paired with low energy requirements, also made it really annoying to deal with as your opponent builds up energy for its stronger attackers on the bench. And now with Irida pairing, it can stay on the bench for a little longer.

So what has caused this card to fallen off in usage? Especially in water decks?
