mtg dog deck commander Secret Lair Deck: Raining Cats and Dogs The deck includes a wide variety of cats and dogs Rin and Seri, Inseparable Commander

Now, there will be some board states where it doesnt do much, but the card has a reasonable base line and will sometimes set up situations where your opponent just has to block to not die, which means they lose their creatures

You only have to slow them down a little for your clock to beat theirs, and Tron doesn't like to react

The downside is that it can be really hard to gain any advantage if you cant get damage onto their characters without making bad trades (losing a powerful character of yours for a cheap one of theirs) or without completely banishing them

These are Legendary creatures with the same color identity as the deck's face card, allowing you to play them instead of the deck's original commander
