This is another nifty combo with Luke Robinson. One of the big drawbacks of Call is that it triggers Attack of Opportunity. Well, Luke can use Gate Box to make sure that's not a problem, and Call also happens to refill your Box if you run out of charges.

I ran this in a Cursed Luke deck and it rapidly became a linchpin of the deck. The combo with Eye of Chaos is nothing to sneeze at. In addition to using the tokens and the charges, you can also use Luke's investigator ability to play Call the Beyond as though you were at an adjacent location, which includes the part where you resolve an ability on the card, meaning you can recharge your Eye and investigate for 2+ clues in an adjacent location for the low price of 1 and 0 resources. Beats the hell out of Recharge in my book.

Another nice interaction is with Close the Circle. Call the Beyond checks for its Uses number rather than the flat 3 of Recharge, and if you're already working with Synergy cards, Uses will often be 4 or 5, meaning you've traded 1 and $0 for 4-5 actions and 3. Sounds pretty good to me. Same logic applies for any other high-Uses card, like Brand of Cthugha or Earthly Serenity.
