Off the top of my head, the only other physical card with this effect is MTG's Letter Bomb which is an Unhinged card, whereas this is meant to be a proper legal card and it's the only card in the entire game with an effect that allows it to do this
A worse pull rate than even Paldea Evolved is grim news, and Im sorry to deliver it

Theres also quite a playful and nostalgic feel to the rounded corners, it reminds me of playing cards from my childhood Pokemon or Uno. They can also be quite practical, when you have a standard pointed corner, it can curl, split or wear over time
that face-up monster cannot attack, its effects are negated, also it cannot be used as material for a Fusion, Synchro, Xyz, or Link Summon
This makes it ideal for collectors who want to display their collection without hiding details
