I know for sure that Computer Search has appeared on the versus ladder at least one time before. I know Jirachi TEU and Dedenne-GX UNB are both being released as promos. I want to invest my RCL packs into a card that will be valuable next set. Any of the vivid boxes, SR energies, tropical beach, etc. are too expensive. Computer Search would suit me well, but I don't want to run the risk of it becoming a versus ladder reward. If Computer Search appears often, please suggest another card. Dowsing Machine would be fine, but Computer Search is prefferable ideally. Thank you.
Computer Search only appeared once on the Versus Ladder: it was awarded between March 12 and April 3, 2018. Because TCG Online has been shut down now, it will never appear again.
