Activate only if three or more cards left your graveyard this turn or if you've sacrificed a Food this turn
This is a highly aggressive deck that focuses on quickly building an army of merfolk creatures, buffing those creatures and adding +1/+1 counters, and then making the entire army unblockable with Herald of Secret Streams
(2021-07-23) Some abilities, like that of Pixie Guide and Barbarian Class, replace rolling a die with rolling extra dice and ignoring the lowest roll
Flying, vigilance, and toxic 2 can help you distribute a good number of poison counters while still having a pretty tough blocker
Even without it, the choice between an effective 4-mana threat or free disruption would have made this a fantastic card
(Damage and effects that say destroy dont destroy it.) I am not its master
