Retaining your Hand is occasionally strong in runs which want to line certain cards up with each other, but Convergence has very limited output other than that Retain, so don't try to force it into a deck which doesn't benefit from it much.
A great utility card. This card is for setting up your combos by getting combo pieces in hand together and giving you the resources to use them. Combo Falling Star with your other attacks, or create even stronger combos from other cards.
