You have all that with Gacha pulls and battle system.

The battle system is too rudimentary to capture the essence of gacha. Insofar as gacha lends itself to gameplay mechanics and not just monetization, deck/teambuilding is absolutely integral. Obviously, the game is a parody, but even as a parody I think it does a poor job of capturing that aspect of building and experimenting with your deck/team. Which is fine, not a criticism of a silly little app, but the person I was responding to asked if this is what real gacha games play like and why people play them and I do not believe this is sufficiently representative.
