Mass Mutiny will let me steal up to one creature from each of my opponents
If I just have my commander and 2 merfolk on board, I'd much rather have Hakbal to explore 3x and then move to attack
(It wont untap during your next untap step.) Whenever you exert a creature, you may discard a card
This card was auctioned by Goldin in 2023 for an incredible $493,230
In addition to the obvious blink-your-own-creatures synergies, it can also clear a blocker for a turn, remove an Ensnaring Bridge to get a big attack through, reset a planeswalker or other card that gains value over several turns (I blinked a Ratchet Bomb multiple times in the semifinals), outright kill any token creature (my favorite is Voice of Resurgence), destroy Walking Ballista (though the Wisp will go down with it), effectively destroy a Chalice of the Void, and perform countless other useful interactions
