i dont see it that much in the wild, it might be a bit underrated. You get to pick the best out of 5 cards and cast it for free later, and the requirement is stupid easy to reach, it essentially read "if you have 3 cratures, cast your Hideway. After that you can still use it as a steady source for +1/+1 counters.
and this is just the baseline, it just gets better if your deck has more synergies with it
