Card effects are not appearing for obtained cards
When viewing a card such as 'negate' via the '+' button (which presumably means unobtained?) The card has an animation to it. When viewing this card via the '✓' button (obtained..?) the effect is not visible on Pixel 4 / Android 10. This appears to occur for all cards.
What you are probably seeing is that one is the normal card in your collection, the other is the "shiny" version that you still need to either craft or get.
Which is a shame as the effects are really cool :)
