Id look elsewhere if I was focused on a type populated by smaller creatures
So now I can replace the venture into the dungeon text with choose one: create a Treasure token, target creature cant attack until your next turn, each player loses 2 life unless they sacrifice an artifact, a creature, or a land, put a +1/+1 counter on target creature, each opponent loses 1 life and you gain 1 life, or target creature gets -4/-0 until your next turn
If you build a deck that can be outmuscled by a 3/3 or where youre running a low creature count (think like, 10-12), this wont fit in well, but in any kind of big monsters simic deck or a ramp deck, this is going to have a home
Usually when that happens, it seems to be because particularly high-value cards were chosen, but I guess that didn't happen here
