People seem to really like Wild Wormhole. SAS currently has it as a 3.5/4. I don't get it. It seems like too much of a liability in most decks I see. If you have any board wipes in your deck, it becomes too risky to play. If your opponent has an empty board, that gets extended to basically all damage actions, as almost all damage actions don't include the word "may". If your deck has artifact destruction, then that is another entire layer to consider. Even if it does let you play a card from outside of logos, you are almost always going to playing the card at a sub-optimal time.
I will admit that it works well with library access. But even then it doesn't feel like such an amazing combo that the card can justify how much everyone else seems to think it is good.
