Junk Anchor (BLC1-EN146) - Battles of Legend: Chapter 1 1st Edition

For a Synchro Summon, you can substitute this card for any 1 "Synchron" Tuner. Once per turn: You can discard 1 card, then target 1 non-Tuner "Junk" monster in your GY; Special Summon that target, and if you do, immediately after this effect resolves, Synchro Summon 1 Synchro Monster that lists a "Synchron" monster as a Tuner, using that monster and this card only. These Synchro Materials are banished instead of being sent to the GY.
