Really? Play 3M - any 3M deck - against mortar bait. Against any half talented player you’ll lose 100% against the hog rider version and most matches against the miner version where they don’t make any mistakes.

The Giant 3M deck is weak to classic logbait, especially versions with Valk over Knight.

Any 3M deck is at a disadvantage against any Golem deck and can only really win if the Golem player is bad, or if Golem player gets a bad rotation/starting hand and 3M has a good start. Lavaloon can be a tossup against the fireball version but is weak to the arrows lightning version.

Oh, and RIP against any deck running 3 spells and almost anything running arrows (Horde becomes automatic liability).

But yeah, 3M is unbeatable (it’s also weak to splashnado of any kind, and I could keep going)
