ReceptionRating · Positive reviews · Number of ratings

M Champions Deck Builder holds the better App Store score, 4.5 against 2.7. That said, the two scores are not equally well evidenced: M Champions Deck Builder has 128 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 88% of iStrobo's written reviews are positive against 54% of M Champions Deck Builder's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iStrobo ships an update every 3 weeks, M Champions Deck Builder weekly. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
