First off - Awesome, awesome, awesome! I always was a pretty huge fan of MTG and Yu-Gi-Oh, so this obviously instantly got my interest!

The one thing that bothers me most after opening a few packs is the fact, that the difference between the different rarity levels is rather small.

This especially strikes on smartphones. But a modern game definitely has to be smartphone-friendly imo!

I think at least legendary should look special, shiny, whatever. You need to be flashed when you open a pack with a legendary. Maybe even make a little animation when you open a legendary card.

What also is weird is the fact, that the element "Life" looks different that the other elements. It took me a few packs to realize that it is a own element and not a gold rarity or something like that. I don't know if this is on purpose for game technical reasons or just because you thought a white border would look stupid with the elements white color. However it's irritating imo.

Also Summoners should somehow look different than normal monsters.

Other than that I only can complain about the fact that I didn't get a single legendary yet :P

Greets,
