A deck made to bridge the gap between cat lovers and dog lovers, Raining Cats and Dogs is pure typal. It continues the trend of double-sided Secret Lair cards. These reversibles usually have cat-based art on one side and dog art on the other.
Rin and Seri, Inseparable is no stranger to Secret Lairs (including a Garfield reskin), and thank goodness. As a card originally released as a buy-a-box promo, one of the cutest themed cards in Magic was bound to be a popular commander, and these help to keep the price down without totally cratering it the way a regular precon printing might.
Jetmir, Nexus of Revels and Jinnie Fay, Jetmir's Second are the other commanders that get the reversible Secret Lair treatment. Jetmir is a popular Naya tokens commander, and Jinnie Fay’s replacement effect is thematic, though it works better in support of a deck that creates tokens reliably.
