It is so rare to see a Mardu deck in cube that this just never gets played despite being good enough to play in any deck with other creatures in it
That makes this card unique on this list for being the only card on the Reserved List on this list
Madam Mims cards require you to send another card to your hand when played
Being a creature means that it has some vulnerabilities that Cori-Steel Cutter doesnt have (Cutter doesnt die to Doom Blade) but the token making mode creating 2 bodies makes it if you get it to Raise the Alarm once, its fine if it gets Doom Bladed, and if it you get it to trigger twice, its on the better side of cubable 3-drops (even with the high competition there.) There was a minor theme in Kaldheim with the cast 2 cards with cards like Clarion Spirit, Codespell Clericand Bloodsky Berserker had such bad floors that only Clarion Spirit got played in cubes, and even then, not that often
But, of course, now, when players "scroll" over the list, they'll find Magic: The Gathering options in play
