If the gift wasn't promised, return that creature to the battlefield under its owner's control with a +1/+1 counter on it at the beginning of the next end step
This number may sound like a lot, but you have to take into account that this represents only 2% of all eligible decks (eligible decks have green in their color identity)
Considering how many effects create these tokens, and how many noncreature spells you can run in this format where half your creature slots are actually equipment, those triggers can end up doing more than half your damage in a lot of games
You cant play it in an aristocrats deck though since it needs to receive damage, so its a fine blocker at best
Furthermore, entire pre-constructed Commander decks are somewhat regularly miscut or off-centered directly from the factory
That is especially relevant with how common Landfall decks are, because now you are getting four triggers instead of two
