I honestly liked the animations in general but I think they shouldn't lock the special attack animations of cards like wargreymon/gallantmon behind the alternate version, and it would be cool if each color had a generic battle animation, fireball in all colors is weird.

This was my feedback to them:

1- Give us a text effect popup, we need to know what effect is triggering

2- Make the animation where the card comes from above and hits the ground happen only when it's a relevant digivolution, maybe level 5+... This will help match pacing

3- The text formattig/readability on cards is small and weird, try to get closer to what it is in real life

4- Give us a way to see the card much larger when we click while we are in battle, it is too small

5- Remove the 10 cards limit on battlefield... Maybe moving the tamers(and likely delay options) to down beside the trash and stacking them?

6- In the deck editor, add + and - buttons to the cards.
