Discard a nonland and that creature grows with a +1/+1 counter
The most obvious example of this is First Edition cards
309.5b If a player ventures into the dungeon while they own a dungeon card in the command zone and their venture marker is on that dungeon cards bottommost room, they remove that dungeon card from the game
What makes this card better is its ability Welcome to my Boat - which allows players to ready all other characters at the same location card as Moana, Born Leader whenever it quests, though they arent allowed to quest for the rest of this turn
It will feel pretty close to a bomb if you can do it consistently A two mana 2/2 with Haste is a solid starting point, and getting a +1/+1 counter or two on Ash is doable
